Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Fannie Mae is a leading source of financing for mortgages in the United States. We are a shareholder-owned corporation organized as a government-sponsored entity (“GSE”) and existing under the Federal National Mortgage Association Charter Act (the “Charter Act” or our “charter”). Our charter is an act of Congress, and we have a purpose under that charter to provide liquidity and stability to the residential mortgage market and to promote access to mortgage credit. Our regulators include the Federal Housing Finance Agency (“FHFA”), the U.S. Department of Housing and Urban Development (“HUD”), the U.S. Securities and Exchange Commission (“SEC”) and the U.S. Department of the Treasury (“Treasury”). The U.S. government does not guarantee our securities or other obligations. We have been under conservatorship, with FHFA acting as conservator, since September 6, 2008. See below and “Note 1, Summary of Significant Accounting Policies” in our annual report on Form 10-K for the year ended December 31, 2021 (“2021 Form 10-K”) for additional information on our conservatorship and the impact of U.S. government support of our business. The unaudited interim condensed consolidated financial statements as of and for the three and nine months ended September 30, 2022 and related notes should be read in conjunction with our audited consolidated financial statements and related notes included in our 2021 Form 10-K. Basis of Presentation The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and with the SEC’s instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and note disclosures required by GAAP for complete consolidated financial statements. In the opinion of management, all adjustments of a normal recurring nature considered necessary for a fair presentation have been included. The accompanying condensed consolidated financial statements include our accounts as well as the accounts of other entities in which we have a controlling financial interest. All intercompany accounts and transactions have been eliminated. Results for the three and nine months ended September 30, 2022 may not necessarily be indicative of the results for the year ending December 31, 2022. Use of Estimates Preparing condensed consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect our reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the dates of our condensed consolidated financial statements, as well as our reported amounts of revenues and expenses during the reporting periods. Management has made significant estimates in a variety of areas including, but not limited to, the allowance for loan losses. Actual results could be different from these estimates. Conservatorship On September 7, 2008, the Secretary of the Treasury and the Director of FHFA announced several actions taken by Treasury and FHFA regarding Fannie Mae, which included: (1) placing us in conservatorship, with FHFA acting as our conservator, and (2) the execution of a senior preferred stock purchase agreement by our conservator, on our behalf, and Treasury, pursuant to which we issued to Treasury both senior preferred stock and a warrant to purchase common stock. Under the Federal Housing Enterprises Financial Safety and Soundness Act of 1992, as amended, including by the Housing and Economic Recovery Act of 2008 (together, the “GSE Act”), the conservator immediately succeeded to (1) all rights, titles, powers and privileges of Fannie Mae, and of any stockholder, officer or director of Fannie Mae with respect to Fannie Mae and its assets, and (2) title to the books, records and assets of any other legal custodian of Fannie Mae. The conservator subsequently issued an order that provided for our Board of Directors to exercise specified functions and authorities. The conservator also provided instructions regarding matters for which conservator decision or notification is required. The conservator retains the authority to amend or withdraw its order and instructions at any time. The conservatorship has no specified termination date and there continues to be significant uncertainty regarding our future, including how long we will continue to exist in our current form, the extent of our role in the market, the level of government support of our business, how long we will be in conservatorship, what form we will have and what ownership interest, if any, our current common and preferred stockholders will hold in us after the conservatorship is terminated and whether we will continue to exist following conservatorship. Under the GSE Act, the Director of FHFA must place us into receivership if they make a written determination that our assets are less than our obligations or if we have not been paying our debts, in either case, for a period of 60 days. In addition, the Director of FHFA may place us into receivership at the Director’s discretion at any time for other reasons set forth in the GSE Act, including if we are critically undercapitalized or if we are undercapitalized and have no reasonable prospect of becoming adequately capitalized. Should we be placed into receivership, different assumptions would be required to determine the carrying value of our assets, which would lead to substantially different financial results. Treasury has made a commitment under the senior preferred stock purchase agreement to provide funding to us under certain circumstances if we have a net worth deficit. We are not aware of any plans of FHFA (1) to fundamentally change our business model, or (2) to reduce the aggregate amount available to or held by the company under our equity structure, which includes the senior preferred stock purchase agreement. Senior Preferred Stock Purchase Agreement and Senior Preferred Stock We discuss more fully our senior preferred stock and the terms of the senior preferred stock purchase agreement, as amended, including Treasury’s funding commitment, in “Note 11, Equity” in our 2021 Form 10-K. Treasury has made a commitment under the senior preferred stock purchase agreement to provide funding to us under certain circumstances if we have a net worth deficit. Pursuant to the senior preferred stock purchase agreement, we have received a total of $119.8 billion from Treasury as of September 30, 2022, and the amount of remaining funding available to us under the agreement is $113.9 billion. We have not received any funding from Treasury under this commitment since the first quarter of 2018. We had positive net worth of $58.8 billion as of September 30, 2022. The dividend provisions of the senior preferred stock permit us to retain increases in our net worth until our net worth exceeds the amount of adjusted total capital necessary for us to meet the capital requirements and buffers under the enterprise regulatory capital framework established by FHFA. The aggregate liquidation preference of the senior preferred stock increased to $177.9 billion as of September 30, 2022 due to the $4.6 billion increase in our net worth in the second quarter of 2022. The aggregate liquidation preference of the senior preferred stock will further increase to $180.3 billion as of December 31, 2022, due to the $2.4 billion increase in our net worth in the third quarter of 2022. Related Parties Because Treasury holds a warrant to purchase shares of Fannie Mae common stock equal to 79.9% of the total number of shares of Fannie Mae common stock, we and Treasury are deemed related parties. FHFA’s control of both Fannie Mae and Freddie Mac has caused Fannie Mae, FHFA and Freddie Mac to be deemed related parties. Additionally, Fannie Mae and Freddie Mac jointly own Common Securitization Solutions, LLC (“CSS”), a limited liability company created to operate a common securitization platform; as a result, CSS is deemed a related party. As a part of our joint ownership, Fannie Mae, Freddie Mac and CSS are parties to a limited liability company agreement that sets forth the overall framework for the joint venture, including Fannie Mae’s and Freddie Mac’s rights and responsibilities as members of CSS. Fannie Mae, Freddie Mac and CSS are also parties to a customer services agreement that sets forth the terms under which CSS provides mortgage securitization services to us and Freddie Mac, including the operation of the common securitization platform, as well as an administrative services agreement. CSS operates as a separate company from us and Freddie Mac, with all funding and limited administrative support services and other resources provided to it by us and Freddie Mac. In the ordinary course of business, Fannie Mae may purchase and sell securities issued by Treasury and Freddie Mac. These transactions occur on the same terms as those prevailing at the time for comparable transactions with unrelated parties. Some of the structured securities we issue are backed in whole or in part by Freddie Mac securities. Fannie Mae and Freddie Mac each have agreed to indemnify the other party for losses caused by: its failure to meet its payment or other specified obligations under the trust agreements pursuant to which the underlying resecuritized securities were issued; its failure to meet its obligations under the customer services agreement; its violations of laws; or with respect to material misstatements or omissions in offering documents, ongoing disclosures and related materials relating to the underlying resecuritized securities. Additionally, we make regular income tax payments to and receive tax refunds from the Internal Revenue Service (“IRS”), a bureau of Treasury. Transactions with Treasury Our administrative expenses were reduced by $4 million for the three months ended September 30, 2022 and 2021, and $11 million and $13 million for the nine months ended September 30, 2022 and 2021, respectively, due to reimbursements from Treasury and Freddie Mac for expenses incurred as program administrator for Treasury’s Home Affordable Modification Program and other initiatives under Treasury’s Making Home Affordable Program. In December 2011, Congress enacted the Temporary Payroll Cut Continuation Act of 2011 (“TCCA”) which, among other provisions, required that we increase our single-family guaranty fees by at least 10 basis points and remit this increase to Treasury. To meet our obligations under the TCCA and at the direction of FHFA, we increased the guaranty fee on all single-family residential mortgages delivered to us by 10 basis points effective April 1, 2012. The resulting fee revenue and expense are recorded in “Interest income: Mortgage loans” and “TCCA fees,” respectively, in our condensed consolidated statements of operations and comprehensive income. In November 2021, the Infrastructure Investment and Jobs Act was enacted, which extended to October 1, 2032 our obligation under the TCCA to collect 10 basis points in guaranty fees on single-family residential mortgages delivered to us and pay the associated revenue to Treasury. In January 2022, FHFA advised us to continue to pay these TCCA fees to Treasury with respect to all single-family loans acquired by us before October 1, 2032, and to continue to remit these amounts to Treasury on and after October 1, 2032 with respect to loans we acquired before this date until those loans are paid off or otherwise liquidated. We recognized TCCA fees of $850 million and $781 million for the three months ended September 30, 2022 and 2021, respectively, and $2.5 billion and $2.3 billion during the nine months ended September 30, 2022 and 2021, respectively, of which $850 million had not been remitted to Treasury as of September 30, 2022. The GSE Act requires us to set aside certain funding obligations, a portion of which is attributable to Treasury’s Capital Magnet Fund. These funding obligations are measured as the product of 4.2 basis points and the unpaid principal balance of our total new business purchases for the respective period, with 35% of this amount payable to Treasury’s Capital Magnet Fund. We recognized a total of $19 million and $46 million in “Other expenses, net” for the three months ended September 30, 2022 and 2021, respectively, and $85 million and $165 million for the nine months ended September 30, 2022 and 2021, respectively, in connection with Treasury’s Capital Magnet Fund, of which $85 million has not been remitted as of September 30, 2022. Transactions with FHFA The GSE Act authorizes FHFA to establish an annual assessment for regulated entities, including Fannie Mae, which is payable on a semi-annual basis (April and October), for FHFA’s costs and expenses, as well as to maintain FHFA’s working capital. We recognized FHFA assessment fees, which are recorded in “Administrative expenses” in our condensed consolidated statements of operations and comprehensive income, of $30 million and $35 million for the three months ended September 30, 2022 and 2021, respectively, and $93 million and $107 million for the nine months ended September 30, 2022 and 2021, respectively. Transactions with CSS and Freddie Mac We contributed capital to CSS, the company we jointly own with Freddie Mac, of $13 million and $15 million for the three months ended September 30, 2022 and 2021, respectively, and $51 million and $60 million for the nine months ended September 30, 2022 and 2021, respectively. Earnings per Share Earnings per share (“EPS”) is presented for basic and diluted EPS. We compute basic EPS by dividing net income attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. However, as a result of our conservatorship status and the terms of the senior preferred stock, no amounts would be available to distribute as dividends to common or preferred stockholders (other than to Treasury as the holder of the senior preferred stock). Net income attributable to common stockholders excludes amounts attributable to the senior preferred stock. Weighted average common shares include 4.7 billion shares for the periods ended September 30, 2022 and 2021 that would have been issued upon the full exercise of the warrant issued to Treasury from the date the warrant was issued through September 30, 2022 and 2021. The calculation of diluted EPS includes all the components of basic earnings per share, plus the dilutive effect of common stock equivalents such as convertible securities and stock options. Weighted average shares outstanding is increased to include the number of additional common shares that would have been outstanding if the dilutive potential New Accounting Guidance Adoption of ASU 2022-02 The Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2022-02, Financial Instruments – Credit Losses (Topic 326) Troubled Debt Restructurings and Vintage Disclosures (“ASU 2022-02”) in March 2022. The amendments in ASU 2022-02 eliminate the accounting guidance for troubled debt restructurings (“TDRs”) by creditors while enhancing disclosure requirements for certain loan restructurings by creditors when a borrower is experiencing financial difficulty. Specifically, rather than applying the recognition and measurement guidance for TDRs, an entity would apply the loan refinancing and restructuring guidance to determine whether a modification or other form of restructuring results in a new loan or a continuation of an existing loan. Additionally, the amendments in this ASU require that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases in the existing vintage disclosures. The ASU is effective for fiscal years beginning after December 15, 2022, for creditors that have adopted the amendments in Accounting Standards Update 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. Early adoption is permitted in any interim period and such election may be made individually to adopt the guidance related to TDRs, including related disclosures, and the presentation of gross write-offs in the vintage disclosures. ASU 2022-02 requires prospective transition for the disclosures related to loan restructurings for borrowers experiencing financial difficulty and the presentation of gross write-offs in the vintage disclosures. The guidance related to the recognition and measurement of TDRs may be adopted on a prospective or modified retrospective transition method. We elected to early adopt the guidance related to the elimination of the recognition and measurement of TDRs and the enhancement of disclosures for loan restructurings for borrowers experiencing financial difficulty as of January 1, 2022, using the prospective transition method. As of our adoption date, all restructurings, including restructurings for borrowers experiencing financial difficulty, are evaluated to determine whether they result in a new loan or a continuation of an existing loan. Loan restructurings for borrowers experiencing financial difficulty are generally accounted for as a continuation of the existing loan as the terms of the restructured loans are typically not at market rates. At adoption of this guidance on January 1, 2022, there was no material impact on our financial statements. When a single-family loan is restructured under ASU 2022-02, we continue to measure impairment on the loan using a discounted cash flow approach that utilizes a prepayment-adjusted discount rate that is based on the loan’s restructured terms. Under the TDR accounting model, we used the discount rate that was in effect prior to the restructuring to measure impairment. Using the interest rate that was in effect prior to the restructuring resulted in the recognition, in the allowance for loan losses, of the economic concession that we granted to borrowers as part of the loan restructuring. Using a post-restructuring interest rate does not result in the recognition of an economic concession in the allowance for loan losses. As we have elected a prospective transition, the economic concession on a loan that was previously restructured and accounted for as a TDR will continue to be measured in our allowance for loan losses using the discount rate that was in effect prior to the restructuring and the economic concession may increase or decrease as we update our cash flow assumptions related to the loan’s expected life. Further, the component of the allowance for loan losses representing economic concessions will decrease as the borrower makes payments in accordance with the restructured terms of the mortgage loan and as the loan is sold, liquidated, or subsequently restructured. In general, the accounting for restructurings made to borrowers experiencing financial difficulty upon adoption of the ASU is consistent with the accounting that we applied to troubled debt restructurings under section 4013 of the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), and the Consolidated Appropriations Act of 2021, which provided temporary relief from the accounting and reporting requirements for certain troubled debt restructurings related to COVID-19 beginning March 2020 through January 1, 2022. We plan to adopt the disclosure guidance related to the presentation of gross write-offs by year of origination in our vintage disclosures upon the effective date of ASU 2022-02, January 1, 2023. We do not expect the adoption of the guidance requiring gross write-offs by year of origination in our vintage disclosures to have a material impact on our financial statements. Fair Value Hedging - Portfolio Layer Method On March 28, 2022, the FASB issued ASU 2022-01, Fair Value Hedging - Portfolio Layer Method, which clarifies the guidance on fair value hedge accounting of interest rate risk portfolios of financial assets. The ASU expands the scope of the current last-of-layer method to allow entities to apply this method, renamed the portfolio layer method, to non-prepayable financial assets and to designate multiple hedge relationships within a single closed portfolio of financial assets. Additionally, the ASU clarifies that basis adjustments related to existing portfolio layer hedge relationships should not be considered when measuring credit losses on the financial assets included in the closed portfolio. Further, the ASU clarifies that any reversal of fair value hedge basis adjustments associated with an actual breach should be recognized in interest income immediately. The ASU is effective for public business entities for fiscal years beginning after December 15, 2022, and interim periods within those years. We plan to adopt this guidance effective January 1, 2023. The adoption of this guidance is not expected to have a material impact on our financial statements.

Consolidations and Transfers of Financial Assets [Abstract]
Consolidations and Transfers of Financial Assets	Consolidations and Transfers of Financial Assets We have interests in various entities that are considered to be variable interest entities (“VIEs”). The primary types of entities are securitization and resecuritization trusts, limited partnerships and special purpose vehicles (“SPVs”). These interests include investments in securities issued by VIEs, such as Fannie Mae MBS created pursuant to our securitization transactions and our guaranty to the entity. We consolidate the substantial majority of our single-class securitization trusts because our role as guarantor and master servicer provides us with the power to direct matters (primarily the servicing of mortgage loans) that impact the credit risk to which we are exposed. In contrast, we do not consolidate single-class securitization trusts when other organizations have the power to direct these activities unless we have the unilateral ability to dissolve the trust. We also do not consolidate our resecuritization trusts unless we have the unilateral ability to dissolve the trust. The underlying assets of our resecuritization trusts include both Fannie Mae securities collateralized solely by mortgage loans held in consolidated trusts as well as uniform mortgage-backed securities (“UMBS ® ”) collateralized with securities issued by Fannie Mae or Freddie Mac. The mortgage loans that serve as collateral for Freddie Mac-issued securities are not held in trusts that are consolidated by Fannie Mae. Unconsolidated VIEs We do not consolidate VIEs when we are not deemed to be the primary beneficiary. Our unconsolidated VIEs include securitization and resecuritization trusts, limited partnerships, and certain SPVs designed to transfer credit risk. The following table displays the carrying amount and classification of our assets and liabilities that relate to our involvement with unconsolidated securitization and resecuritization trusts. As of September 30, 2022 December 31, 2021 (Dollars in millions) Assets and liabilities recorded in our condensed consolidated balance sheets related to unconsolidated mortgage-backed trusts: Investments in securities $ 3,713 $ 4,709 Other assets 41 35 Other liabilities (48) (41) Net carrying amount $ 3,706 $ 4,703 Our maximum exposure to loss generally represents the greater of our carrying value in the entity or the unpaid principal balance of the assets covered by our guaranty. Our involvement in unconsolidated resecuritization trusts may give rise to additional exposure to loss depending on the type of resecuritization trust. Fannie Mae non-commingled resecuritization trusts are backed entirely by Fannie Mae MBS. These non-commingled single-class and multi-class resecuritization trusts are not consolidated and do not give rise to any additional exposure to loss as we already consolidate the underlying collateral. Fannie Mae commingled resecuritization trusts are backed in whole or in part by Freddie Mac securities. The guaranty that we provide to these commingled resecuritization trusts may increase our exposure to loss to the extent that we are providing a guaranty for the timely payment and interest on the underlying Freddie Mac securities that we have not previously guaranteed. Our maximum exposure to loss for these unconsolidated trusts is measured by the amount of Freddie Mac securities that are held in these resecuritization trusts. Our maximum exposure to loss related to unconsolidated securitization and resecuritization trusts, which includes but is not limited to our exposure to these Freddie Mac securities, was approximately $246 billion and $220 billion as of September 30, 2022 and December 31, 2021, respectively. The total assets of our unconsolidated securitization and resecuritization trusts were approximately $250 billion as of September 30, 2022 and December 31, 2021. The maximum exposure to loss for our unconsolidated limited partnerships and similar legal entities, which consist of low-income housing tax credit (“LIHTC”) investments, community investments and other entities, was $399 million and the related net carrying value was $395 million as of September 30, 2022. As of December 31, 2021, the maximum exposure to loss was $292 million and the related net carrying value was $288 million. The total assets of these limited partnership investments were $4.1 billion and $3.7 billion as of September 30, 2022 and December 31, 2021, respectively. The maximum exposure to loss related to our involvement with unconsolidated SPVs that transfer credit risk represents the unpaid principal balance and accrued interest payable of obligations issued by the Connecticut Avenue Securities ® (“CAS”) and Multifamily Connecticut Avenue Securities TM (“MCAS TM ”) SPVs. The maximum exposure to loss related to these unconsolidated SPVs was $17.4 billion and $10.4 billion as of September 30, 2022 and December 31, 2021, respectively. The total assets related to these unconsolidated SPVs were $17.5 billion and $10.4 billion as of September 30, 2022 and December 31, 2021, respectively. Transfers of Financial Assets We issue Fannie Mae MBS through portfolio securitization transactions by transferring pools of mortgage loans or mortgage-related securities to one or more trusts or special purpose entities. We are considered to be the transferor when we transfer assets from our own retained mortgage portfolio in a portfolio securitization transaction. For the three months ended September 30, 2022 and 2021, the unpaid principal balance of portfolio securitizations was $56.1 billion and $140.1 billion, respectively. For the nine months ended September 30, 2022 and 2021, the unpaid principal balance of portfolio securitizations was $235.9 billion and $554.0 billion, respectively. The substantial majority of these portfolio securitization transactions generally do not qualify for sale treatment. Portfolio securitization trusts that do qualify for sale treatment primarily consist of loans that are guaranteed or insured, in whole or in part, by the U.S. government. We retain interests from the transfer and sale of mortgage-related securities to unconsolidated single-class and multi-class portfolio securitization trusts. As of September 30, 2022, the unpaid principal balance of retained interests was $1.0 billion and its related fair value was $1.5 billion. As of December 31, 2021, the unpaid principal balance of retained interests was $1.1 billion and its related fair value was $2.0 billion. For the three months ended September 30, 2022 and 2021, the principal, interest and other fees received on retained interests was $86 million and $139 million, respectively. For the nine months ended September 30, 2022 and 2021, the principal, interest and other fees received on retained interests was $308 million and $426 million, respectively.

Mortgage Loans

Mortgage Loans	9 Months Ended
	Sep. 30, 2022
SEC Schedule, 12-29, Real Estate Companies, Investment in Mortgage Loans on Real Estate [Abstract]
Mortgage Loans	Mortgage Loans We own single-family mortgage loans, which are secured by four or fewer residential dwelling units, and multifamily mortgage loans, which are secured by five or more residential dwelling units. We classify these loans as either held for investment (“HFI”) or held for sale (“HFS”). For purposes of our notes to the condensed consolidated financial statements, we report the amortized cost of HFI loans for which we have not elected the fair value option at the unpaid principal balance, net of unamortized premiums and discounts, hedge-related basis adjustments, other cost basis adjustments, and accrued interest receivable in these “Note 3, Mortgage Loans” disclosures. For purposes of our condensed consolidated balance sheets, we present accrued interest receivable, net separately from the amortized cost of our loans held for investment. We report the carrying value of HFS loans at the lower of cost or fair value and record valuation changes in “Investment gains (losses), net” in our condensed consolidated statements of operations and comprehensive income. For purposes of the single-family mortgage loan disclosures below, we display loans by class of financing receivable type. Financing receivable classes used for disclosure consist of: “20- and 30-year or more, amortizing fixed-rate,” “15-year or less, amortizing fixed-rate,” “Adjustable-rate,” and “Other.” The “Other” class primarily consists of reverse mortgage loans, interest-only loans, negative-amortizing loans and second liens. The following table displays the carrying value of our mortgage loans and allowance for loan losses. As of September 30, 2022 December 31, 2021 (Dollars in millions) Single-family $ 3,638,342 $ 3,495,573 Multifamily 420,312 403,452 Total unpaid principal balance of mortgage loans 4,058,654 3,899,025 Cost basis and fair value adjustments, net 54,376 74,846 Allowance for loan losses for HFI loans (8,302) (5,629) Total mortgage loans (1) $ 4,104,728 $ 3,968,242 (1) Excludes $9.2 billion and $9.1 billion of accrued interest receivable, net of allowance as of September 30, 2022 and December 31, 2021. The following table displays information about our purchase of HFI loans, redesignation of loans from HFI to HFS and the sales of mortgage loans during the period. For the Three Months Ended September 30, For the Nine Months Ended September 30, 2022 2021 2022 2021 (Dollars in millions) Purchase of HFI loans: Single-family unpaid principal balance $ 117,686 $ 296,410 $ 529,453 $ 1,070,136 Multifamily unpaid principal balance 15,943 16,282 50,627 48,580 Single-family loans redesignated from HFI to HFS: Amortized cost $ 1,726 $ 3,427 $ 6,099 $ 12,844 Lower of cost or fair value adjustment at time of redesignation (1) (196) (47) (418) (247) Allowance reversed at time of redesignation 80 165 298 1,350 Single-family loans sold: Unpaid principal balance $ 1,919 $ 3,063 $ 6,229 $ 10,588 Realized gains, net 20 300 91 955 (1) Consists of the write-off against the allowance at the time of redesignation. The amortized cost of single-family mortgage loans for which formal foreclosure proceedings were in process was $4.6 billion as of September 30, 2022 and $4.4 billion as of December 31, 2021. As a result of our various loss mitigation and foreclosure prevention efforts, we expect that a portion of the loans in the process of formal foreclosure proceedings will not ultimately foreclose. Aging Analysis The following tables display an aging analysis of the total amortized cost of our HFI mortgage loans by portfolio segment and class of financing receivable, excluding loans for which we have elected the fair value option.

Multifamily seriously delinquent loans are loans that are 60 days or more past due. (2) Reverse mortgage loans included in “Other” are not aged due to their nature and are included in the current column. (3) Multifamily loans 60-89 days delinquent are included in the seriously delinquent column. Credit Quality Indicators The following tables display the total amortized cost of our single-family HFI loans by class of financing receivable, year of origination and credit quality indicator, excluding loans for which we have elected the fair value option. The estimated mark-to-market loan-to-value (“LTV”) ratio is a primary factor we consider when estimating our allowance for loan losses for single-family loans. As LTV ratios increase, the borrower's equity in the home decreases, which may negatively affect the borrower's ability to refinance or to sell the property for an amount at or above the outstanding balance of the loan.

(2) The aggregate estimated mark-to-market LTV ratio is based on the unpaid principal balance of the loan divided by the estimated current value of the property as of the end of each reported period, which we calculate using an internal valuation model that estimates periodic changes in home value. The following tables display the total amortized cost of our multifamily HFI loans by year of origination and credit-risk rating, excluding loans for which we have elected the fair value option. Property rental income and property valuations are key inputs to our internally assigned credit risk ratings.

(2) Represents loans classified as “Substandard” or “Doubtful.” Loans classified as “Substandard” have a well-defined weakness that jeopardizes the timely full repayment. “Doubtful” refers to a loan with a weakness that makes collection or liquidation in full highly questionable and improbable based on existing conditions and values. We had loans with an amortized cost of $15 million classified as doubtful as of September 30, 2022 and loans with an amortized cost of less than $1 million classified as doubtful as of December 31, 2021. Loss Mitigation Options for Borrowers Experiencing Financial Difficulty As part of our loss mitigation activities, we may agree to modify the contractual terms of a loan to a borrower experiencing financial difficulty. In addition to loan modifications, we also provide other loss mitigation options to assist borrowers who experience financial difficulties. Below we provide disclosures relating to loan restructurings where borrowers were experiencing financial difficulty, including restructurings that resulted in an insignificant payment delay. The disclosures exclude loans classified as held for sale and those for which we have elected the fair value option. Single-Family Loan Restructurings We offer several types of restructurings to single-family borrowers that may result in a payment delay, interest rate reduction, term extension, or combination thereof. We do not typically offer principal forgiveness. We offer the following types of restructurings to single-family borrowers that only result in a payment delay: • a forbearance plan is a short-term loss mitigation option which grants a period of time (typically 3-month increments) during which the borrower’s monthly payment obligations are reduced or suspended. A forbearance plan does not impact our reporting of when a loan is considered past due, which remains based on the contractual terms of the loan. Borrowers may exit a forbearance plan by repaying all past due amounts to fully reinstate the loan, paying off the loan in full, or entering into another loss mitigation option, such as a repayment plan, a payment deferral, or a loan modification. The vast majority of forbearance plans offered since 2020 relate to a COVID-19-related financial hardship where we have authorized our servicers to offer a forbearance plan for up to 18 months for eligible borrowers; • a repayment plan is a short-term loss mitigation option that allows borrowers a specific period of time to return the loan to current status by paying the regular monthly payment plus additional agreed-upon delinquent amounts (generally for a period up to 12 months and the monthly repayment plan amount must not exceed 150% of the contractual mortgage payment). A repayment plan does not impact our reporting of when a loan is considered past due, which remains based on the contractual terms of the loan. At the end of the repayment plan, the borrower resumes making the regular monthly payment; and • a payment deferral is a loss mitigation option which defers the repayment of the delinquent principal and interest payments and other eligible default-related amounts that were advanced on behalf of the borrower by converting them into a non-interest-bearing balance due at the earlier of the payoff date, the maturity date, or sale or transfer of the property. The remaining mortgage terms, interest rate, payment schedule, and maturity date remain unchanged, and no trial period is required. The number of months of payments deferred varies based on the types of hardships the borrower is facing. We also offer single-family borrowers loan modifications, which contractually change the terms of the loan. Our loan modification programs generally require completion of a trial period of three to four months where the borrower makes reduced monthly payments prior to receiving the modification. During the trial period, the mortgage loan is not contractually modified and continues to be reported as past due according to its contractual terms. The reduced payments that are made by the borrower during the trial period will result in a payment delay with respect to the original contractual terms of the loan. After successful completion of the trial period, and the borrower’s execution of a modification agreement, the mortgage loan is contractually modified. Our loan modifications include the following concessions: • capitalization of past due amounts, a form of payment delay, which capitalizes interest and other eligible default related amounts that were advanced on behalf of the borrower that are past due into the unpaid principal balance; and • a term extension, which typically extends the contractual maturity date of the loan to 40 years from the effective date of the modification. In addition to these concessions, loan modifications may also include an interest rate reduction, which reduces the contractual interest rate of the loan, or a principal forbearance, which is another form of payment delay that includes forbearing repayment of a portion of the principal balance as a non-interest bearing amount that is due at the earlier of the payoff date, the maturity date, or sale or transfer of the property. Multifamily Loan Restructurings For multifamily borrowers, loan restructurings include short-term forbearance plans and loan modification programs, which primarily result in term extensions of up to one year with no change to the loan’s interest rate. In certain cases, we may make more significant modifications of terms for borrowers experiencing financial difficulty, such as reducing the interest rate, converting to interest-only payments, extending the maturity for longer than one year, providing principal forbearance, or some combination of these terms. Restructurings for Borrowers Experiencing Financial Difficulty The following table displays the amortized cost of HFI mortgage loans that were restructured during the three and nine months ended September 30, 2022, presented by portfolio segment and class of financing receivable.

(3) Excludes $205 million and $3.0 billion for the three and nine months ended September 30, 2022, respectively, for loans that received a loss mitigation activity during the period that paid off, repurchased or sold prior to period end. Also excludes loans that liquidated either through foreclosure, deed-in-lieu of foreclosure, or a short sale. Loans may move from one category to another, as a result of the restructuring(s) they received during the period. Our estimate of future credit losses uses a lifetime methodology, derived from modeled loan performance based on the historical experience of loans with similar risk characteristics, adjusted to reflect current conditions, our current loss mitigation activities and reasonable and supportable forecasts. The credit loss model considers extensive historical loss experience, which would include the impact of the loss mitigation programs that we offer to borrowers experiencing financial difficulty, and also includes the impact of projected loss severities as a result of a loan default. The manner in which these loss mitigation programs are factored into our loss estimates do not vary by portfolio segment. The following tables summarize the financial impacts of loan modifications and payment deferrals made to single-family HFI loans during the three and nine months ended September 30, 2022, presented by class of financing receivable. We discuss the qualitative impacts of forbearance plans, repayment plans, and trial modifications earlier in this footnote. As a result, those loss mitigation options are excluded from the table below.

The following tables display the amortized cost of HFI loans that received a completed modification or payment deferral on or after January 1, 2022, the date we adopted ASU 2022-02, through September 30, 2022 and that defaulted in the period presented. The substantial majority of loans that received a completed modification or a payment deferral during the third quarter of 2022 did not default during the period. For purposes of this disclosure, we define loans that had a payment default as single-family loans with completed modifications that are two or more months delinquent during the period; or multifamily loans with completed modifications that are one or more months delinquent during the period. For loans that receive a forbearance plan, repayment plan or trial modification, these loss mitigation options generally remain in default until the loan is no longer delinquent as a result of the payment of all past-due amounts or as a result of a loan modification or payment deferral. Therefore, forbearance plans, repayment plans and trial modifications are not included in default tables below.

Troubled Debt Restructuring Disclosures Prior to Our Adoption of ASU 2022-02 Prior to our adoption of ASU 2022-02, we accounted for a modification to the contractual terms of a loan that resulted in granting a concession to a borrower experiencing financial difficulties as a TDR. In addition to formal loan modifications, we accounted for informal restructurings as a TDR if we deferred more than three missed payments to a borrower experiencing financial difficulty. We also classified bankruptcy relief provided to certain borrowers as TDRs. However, our TDR accounting described herein was suspended for most of our loss mitigation activities through our election to account for certain eligible loss mitigation activities occurring between March 2020 and January 1, 2022 under the COVID-19 relief granted pursuant to the CARES Act and the Consolidated Appropriations Act of 2021. On January 1, 2022, we adopted ASU 2022-02, which eliminated TDR accounting prospectively for all restructurings occurring on or after January 1, 2022. Loans that were restructured in a TDR prior to the adoption of ASU 2022-02 will continue to be accounted for under the historical TDR accounting until the loan is paid off, liquidated or subsequently modified. See “Note 1, Summary of Significant Accounting Policies” in our 2021 Form 10-K for more information on the COVID-19 relief from TDR accounting and disclosure requirements, and “Note 1, Summary of Significant Accounting Policies” in this report for more information on our adoption of ASU 2022-02. The substantial majority of the loan modifications accounted for as TDRs resulted from a payment delay, term extension, interest rate reduction or a combination thereof. The average term extension of a single-family modified loan was 151 months and the average interest rate reduction was 0.56 percentage points for the three months ended September 30, 2021. During the nine months ended September 30, 2021, the average term extension of a single-family modified loan was 146 months and the average interest rate reduction was 0.57 percentage points. The following table displays the number of loans and amortized cost of loans classified as a TDR during the period.

For purposes of this disclosure, we defined loans that had a payment default as: single-family and multifamily loans with completed modifications that liquidated during the period, either through foreclosure, deed-in-lieu of foreclosure, or a short sale; single-family loans with completed modifications that are two or more months delinquent during the period; or multifamily loans with completed modifications that are one or more months delinquent during the period.

For single-family loans, we continue to accrue interest income beyond six months of delinquency provided that the collection of principal and interest continues to be reasonably assured. Multifamily loans that are in a forbearance arrangement are placed on nonaccrual status when the borrower is six months past due unless the loan is both well secured and in the process of collection. For single-family and multifamily loans in a forbearance arrangement that are placed on nonaccrual status, cash payments for interest are applied as a reduction of accrued interest receivable until the receivable has been reduced to zero, and then recognized as interest income. For loans that have been negatively impacted by COVID-19, we establish a valuation allowance for expected credit losses on the accrued interest receivable balance applying the process that we have established for both single-family and multifamily loans. The credit expense related to this valuation allowance is classified as a component of the provision for credit losses. Accrued interest receivable is written off when the amount is deemed to be uncollectible. Loans that are in active forbearance plans are not evaluated for write-off. For loans not subject to the COVID-19-related guidance, we have elected not to measure an allowance for credit losses on accrued interest receivable balances as we have a nonaccrual policy to ensure the timely reversal of unpaid accrued interest. See “Note 4, Allowance for Loan Losses” for additional information about our current-period provision for loan losses. For loans not subject to the COVID-19-related nonaccrual policy we discontinue accruing interest when we believe collectability of principal and interest is not reasonably assured, which for a single-family loan we have determined, based on our historical experience, to be when the loan becomes two months or more past due according to its contractual terms. Single-family and multifamily loans are reported past due if a full payment of principal and interest is not received within one month of its due

Allowance for Loan Losses

Allowance for Loan Losses	9 Months Ended

Receivables [Abstract]
Allowance for Loan Losses	Allowance for Loan LossesWe maintain an allowance for loan losses for HFI loans held by Fannie Mae and by consolidated Fannie Mae MBS trusts, excluding loans for which we have elected the fair value option. When calculating our allowance for loan losses, we consider the unpaid principal balance, net of unamortized premiums and discounts, and other cost basis adjustments of HFI loans at the balance sheet date. We record write-offs as a reduction to our allowance for loan losses at the point of foreclosure, completion of a short sale, upon the redesignation of nonperforming and reperforming loans from HFI to HFS or when a loan is determined to be uncollectible. The following table displays changes in our allowance for single-family loans, multifamily loans and total allowance for loan losses. The benefit or provision for loan losses excludes provision for accrued interest receivable losses, guaranty loss reserves and credit losses on available-for-sale (“AFS”) debt securities. Cumulatively, these amounts are recognized as “Benefit (provision) for credit losses” in our condensed consolidated statements of operations and comprehensive income. For the Three Months Ended September 30, For the Nine Months Ended September 30, 2022 2021 2022 2021 (Dollars in millions) Single-family allowance for loan losses: Beginning balance $ (5,389) $ (6,064) $ (4,950) $ (9,344) Benefit (provision) for loan losses (2,339) 839 (2,869) 4,003 Write-offs 289 51 564 271 Recoveries (65) (133) (182) (212) Other 16 (8) (51) (33) Ending Balance $ (7,488) $ (5,315) $ (7,488) $ (5,315) Multifamily allowance for loan losses: Beginning balance $ (680) $ (1,050) $ (679) $ (1,208) Benefit (provision) for loan losses (169) 45 (153) 175 Write-offs 39 7 39 54 Recoveries (4) (21) (21) (40) Ending Balance $ (814) $ (1,019) $ (814) $ (1,019) Total allowance for loan losses: Beginning balance $ (6,069) $ (7,114) $ (5,629) $ (10,552) Benefit (provision) for loan losses (2,508) 884 (3,022) 4,178 Write-offs 328 58 603 325 Recoveries (69) (154) (203) (252) Other 16 (8) (51) (33) Ending Balance $ (8,302) $ (6,334) $ (8,302) $ (6,334) Our benefit or provision for loan losses can vary substantially from period to period based on a number of factors, such as changes in actual and forecasted home prices or property valuations, fluctuations in actual and forecasted interest rates, borrower payment behavior, events such as natural disasters or pandemics, the type, volume and effectiveness of our loss mitigation activities, including forbearances and loan modifications, the volume of foreclosures completed, and the volume and pricing of loans redesignated from HFI to HFS. Our benefit or provision can also be impacted by updates to the models, assumptions, and data used in determining our allowance for loan losses. In recent periods, changes in actual and projected interest rates have been a meaningful driver of our benefit or provision for loan losses as these changes drive prepayment speeds and impact the measurement of the economic concessions granted to borrowers on modified loans. Pursuant to our adoption of ASU 2022-02 on January 1, 2022, we prospectively discontinued TDR accounting and no longer measure the economic concession for restructurings occurring on or after the adoption date. This accounting also results in the elimination of any existing economic concession related to a loan that was previously designated as a TDR if such loan is restructured on or after January 1, 2022. See “Note 1, Summary of Significant Accounting Policies—New Accounting Guidance” for more information about our adoption of ASU 2022-02. Our single-family provision for loan losses for the three months ended September 30, 2022 was primarily driven by a provision from actual and forecasted home prices. Actual home prices declined slightly on a national basis in the third quarter of 2022. In addition, our home price forecast worsened compared with the second quarter of 2022. While our second quarter 2022 home price forecast estimated home price growth in the second half of 2022 and in 2023, our current home price forecast estimates additional home price declines in the fourth quarter of 2022 and throughout 2023. Lower home prices increase the likelihood that loans will default and increase the amount of credit loss on loans that do default, which increases our estimate of losses and ultimately increases our loss reserves and provision for loan losses. The largest drivers of our single-family provision for loan losses for the nine months ended September 30, 2022 were: • Provision from actual and forecasted home prices in the third quarter of 2022 discussed above was the largest driver of our single-family provision for loan losses for the first nine months of 2022. The impact of this home-price related provision in the third quarter of 2022 was partially offset by a benefit from actual and expected home price growth in each of the first and second quarters of 2022. During the first half of the year, our forecasted home prices were positive for the second half of 2022 through 2023. In addition, we observed strong actual home price growth through the second quarter of 2022 . • Provision from higher actual and projected interest rates as of September 30, 2022 compared with December 31, 2021. As mortgage rates increase, we expect a decrease in future prepayments on single-family loans, including modified loans accounted for as TDRs. Lower expected prepayments extend the expected lives of these TDR loans, which increases the expected impairment relating to economic concessions provided on them, resulting in a provision for loan losses. • Provision from changes in loan activity, which includes provision on newly acquired loans. Throughout the first nine months of 2022, refinance loan volumes have continued to decline and purchase loans have increased as a percentage of acquisitions compared to the first nine months of 2021. As we shift to more purchase loans, the credit profile of our acquisitions weakens as purchase loans generally have higher origination LTV ratios than refinance loans. This drove a higher estimated risk of default and loss severity in the allowance and therefore a higher loan loss provision for those loans at the time of acquisition. In addition, for the third quarter of 2022, our loan loss provision also increased as our more negative home price forecast impacted our estimate of losses on newly acquired loans. The primary factors that contributed to our single-family benefit for loan losses for the three months ended September 30, 2021 were: • Benefit from actual and forecasted home price growth . For the three months ended September 30, 2021, actual home price growth continued to be strong. We also increased our expectations for home price growth on a national basis for full-year 2021. • Benefit from changes in assumptions regarding COVID-19 forbearance and loan delinquencies. For the three months ended September 30, 2021, the benefit was driven by the removal of the remaining non-modeled adjustment related to COVID-19 as discussed below. T he primary factors that contributed to our single-family benefit for loan losses for the nine months ended September 30, 2021 were: • Benefit from actual and forecasted home price growth which was robust throughout 2021 . • Benefit from the redesignation of certain nonperforming and reperforming single-family loans from HFI to HFS. We redesignated certain nonperforming and reperforming single-family loans from HFI to HFS, as we no longer intended to hold them for the foreseeable future or to maturity. Upon redesignation of these loans, we recorded the loans at the lower of cost or fair value with a write-off against the allowance for loan losses. Amounts recorded in the allowance related to these loans exceeded the amounts written off, resulting in a net benefit for loan losses. • Benefit from changes in assumptions regarding COVID-19 forbearance and loan delinquencies. During the first and second quarters of 2021, management used its judgment to supplement the loss projections developed by our credit loss model to account for uncertainty arising from the COVID-19 pandemic that was not represented in historical data or otherwise captured by our credit model. As of September 30, 2021, management removed the remaining non-modeled adjustment as the effects of the economic stimulus, the vaccine rollout, and the effectiveness of COVID-19-related loss mitigation strategies became much less uncertain. Specifically, the decrease in uncertainty as of September 30, 2021 compared with the end of 2020 was primarily driven by the passage of the American Rescue Plan Act of 2021 and the broad implementation of the COVID-19 vaccination program in the United States, which contributed to a significant increase in business activity and helped support continued economic growth. There was also a steady decline in the number of borrowers in a COVID-19- related forbearance, lessening expectations of loan losses. Additionally, we believed the array of possible future economic environments included in our credit model, which captured scenarios that may be remote, combined with data consumed over the course of the COVID-19 pandemic removed the need to continue to supplement modeled results. The impact of these factors was partially offset by a provision for higher actual and projected interest rates, which reduced our single-family benefit for loan losses recognized for the nine months ended September 30, 2021. Actual and projected interest rates were higher as of September 30, 2021 compared with December 31, 2020. The increase in single-family write-offs for the three and nine months ended September 30, 2022 compared with the three and nine months ended September 30, 2021 was primarily driven by higher lower-of-cost-or-market adjustments at the time of loan redesignation due to price declines on our HFS loans as interest rates rose. In addition, we had higher write-offs on single-family loans that went to foreclosure for the three and nine months ended September 30, 2022 due to increased foreclosure activity as well as a decrease in the estimated proceeds from sales of REO as a result of the recent decline in home prices. The largest driver of our multifamily provision for loan losses for the three and nine months ended September 30, 2022, was a provision for higher actual and projected interest rates. Rising interest rates may reduce the ability of multifamily borrowers to refinance their loans, which often have balloon balances at maturity, increasing our provision for loan losses. Additionally, rising interest rates also increase the chance that multifamily borrowers with adjustable-rate mortgages may default due to higher payments if the property net operating income is not increasing at a similar rate. The primary factors that contributed to our multifamily benefit for loan losses for the three and nine months ended September 30, 2021 were: • Benefit from actual and projected economic data. For the three and nine months ended September 30, 2021, property value forecasts increased due to continued demand for multifamily housing. In addition, improved job growth led to an increase in projected average property net operating income, which reduced the probability of loan defaults resulting in a benefit for loan losses for the quarter and year-to-date. • Benefit from lower expected loan losses as a result of the COVID-19 pandemic. Similar to our single-family benefit for loan losses described above, for the first and second quarters of 2021 management used its judgment to supplement the loss projections developed by our credit loss model to account for uncertainty arising from the COVID-19 pandemic. As of September 30, 2021, management removed the remaining non-modeled adjustment as the effects of the economic stimulus, the vaccine rollout, and the effectiveness of COVID-19-related loss mitigation strategies were less uncertain.

We define the amortized cost basis of our AFS securities as unpaid principal balance, net of unamortized premiums and discounts, and other cost basis adjustments. We record an allowance for credit losses for AFS securities that reflects the impairment for credit losses, which are limited to the amount that fair value is less than the amortized cost. Impairment due to non-credit losses are recorded as unrealized losses within “Other comprehensive loss.” The following tables display the amortized cost, allowance for credit losses, gross unrealized gains and losses in accumulated other comprehensive income (loss) (“AOCI”), and fair value by major security type for AFS securities.

(3) Total allowance for credit losses was less than $0.5 million as of December 31, 2021. Our Fannie Mae and other agency AFS securities consist of securities issued by us, Freddie Mac, or Ginnie Mae. The principal and interest on these securities are guaranteed by the issuing agency. We believe that the guaranty provided by the issuing agency, the support provided to the agencies by the U.S. government, the importance of the agencies to the liquidity and stability in the secondary mortgage market, and the long history of zero credit losses on agency mortgage-related securities are all indicators that there are currently no credit losses on these securities, even if the security is in an unrealized loss position. In addition, we generally hold these securities that are in an unrealized loss position to recovery. As a result, unless we intend to sell the security, we do not recognize an allowance for credit losses on agency mortgage-related securities. The following table displays additional information regarding gross unrealized losses and fair value by major security type for AFS securities in an unrealized loss position, excluding allowance for credit losses.

Guarantees [Abstract]
Financial Guarantees	Financial Guarantees We recognize a guaranty obligation for our obligation to stand ready to perform on our guarantees to unconsolidated trusts and other guaranty arrangements. These off-balance sheet guarantees expose us to credit losses primarily relating to the unpaid principal balance of our unconsolidated Fannie Mae MBS and other financial guarantees. The maximum remaining contractual term of our guarantees is 30 years; however, the actual term of each guaranty may be significantly less than the contractual term based on the prepayment characteristics of the related mortgage loans. We measure our guaranty reserve for estimated credit losses for off-balance sheet exposures over the contractual period for which they are exposed to the credit risk, unless that obligation is unconditionally cancellable by the issuer. As the guarantor of structured securities backed in whole or in part by Freddie Mac-issued securities, we extend our guaranty to the underlying Freddie Mac securities in our resecuritization trusts. However, Freddie Mac continues to guarantee the payment of principal and interest on the underlying Freddie Mac securities that we have resecuritized. When we began issuing UMBS, we entered into an indemnification agreement under which Freddie Mac agreed to indemnify us for losses caused by its failure to meet its payment or other specified obligations under the trust agreements pursuant to which the underlying resecuritized securities were issued. As a result, and due to the funding commitment available to Freddie Mac through its senior preferred stock purchase agreement with Treasury, we have concluded that the associated credit risk is negligible. Accordingly, we exclude from the following table Freddie Mac securities backing unconsolidated Fannie Mae-issued structured securities of approximately $239.9 billion and $212.3 billion as of September 30, 2022 and December 31, 2021, respectively. The following table displays our off-balance sheet maximum exposure, guaranty obligation recognized in our condensed consolidated balance sheets and the potential maximum recovery from third parties through available credit enhancements and recourse related to our financial guarantees.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments Derivative instruments are an integral part of our strategy in managing interest-rate risk. Derivative instruments may be privately-negotiated, bilateral contracts or they may be listed and traded on an exchange. We refer to our derivative transactions made pursuant to bilateral contracts as our over-the-counter (“OTC”) derivative transactions and our derivative transactions accepted for clearing by a derivatives clearing organization as our cleared derivative transactions. We typically do not settle the notional amount of our risk management derivatives; rather, notional amounts provide the basis for calculating actual payments or settlement amounts. The derivative contracts we use for interest-rate risk management purposes consist primarily of interest-rate swaps and interest-rate options. See “Note 8, Derivative Instruments” in our 2021 Form 10-K for additional information on interest-rate risk management. We account for certain forms of credit risk transfer transactions as derivatives. In our credit risk transfer transactions, a portion of the credit risk associated with losses on a reference pool of mortgage loans is transferred to a third party. We enter into derivative transactions that are associated with some of our credit risk transfer transactions, whereby we manage investment risk to guarantee that certain unconsolidated VIEs have sufficient cash flows to pay their contractual obligations. We enter into forward purchase and sale commitments that lock in the future delivery of mortgage loans and mortgage-related securities at a fixed price or yield. Certain commitments to purchase mortgage loans and purchase or sell mortgage-related securities meet the criteria of a derivative. We typically settle the notional amount of our mortgage commitments that are accounted for as derivatives. We recognize all derivatives as either assets or liabilities in our condensed consolidated balance sheets at their fair value on a trade date basis. Fair value amounts, which are (1) netted to the extent a legal right of offset exists and is enforceable by law at the counterparty level and (2) inclusive of the right or obligation associated with the cash collateral posted or received, are recorded in “Other assets” or “Other liabilities” in our condensed consolidated balance sheets. See “Note 12, Fair Value” for additional information on derivatives recorded at fair value. We present cash flows from derivatives as operating activities in our condensed consolidated statements of cash flows. Fair Value Hedge Accounting As discussed in “Note 1, Summary of Significant Accounting Policies” in our 2021 Form 10-K, we implemented a fair value hedge accounting program in January 2021. Pursuant to this program, we may designate certain interest-rate swaps as hedging instruments in hedges of the change in fair value attributable to the designated benchmark interest rate for certain closed pools of fixed-rate, single-family mortgage loans or our funding debt. For hedged items in qualifying fair value hedging relationships, changes in fair value attributable to the designated risk are recognized as a basis adjustment to the hedged item. We also report changes in the fair value of the derivative hedging instrument in the same condensed consolidated statements of operations and comprehensive income line item used to recognize the earnings effect of the hedged item’s basis adjustment. The objective of our fair value hedges is to reduce GAAP earnings volatility related to changes in benchmark interest rates. Notional and Fair Value Position of our Derivatives The following table displays the notional amount and estimated fair value of our asset and liability derivative instruments, including derivative instruments designated as hedges.

Derivative Counterparty Credit Exposure Our derivative counterparty credit exposure relates principally to interest-rate derivative contracts. We are exposed to the risk that a counterparty in a derivative transaction will default on payments due to us, which may require us to seek a replacement derivative from a different counterparty. This replacement may be at a higher cost, or we may be unable to find a suitable replacement. We manage our derivative counterparty credit exposure relating to our risk management derivative transactions mainly through enforceable master netting arrangements, which allow us to net derivative assets and liabilities with the same counterparty or clearing organization and clearing member. For our OTC derivative transactions, we require counterparties to post collateral, which may include cash, U.S. Treasury securities, agency debt and agency mortgage-related securities.

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting We have two reportable business segments, which are based on the type of business activities each perform: Single-Family and Multifamily. Results of our two business segments are intended to reflect each segment as if it were a stand-alone business. The sum of the results for our two business segments equals our condensed consolidated results of operations. For additional information related to our business segments, including basis of organization and other segment activities, see “Note 10, Segment Reporting” in our 2021 Form 10-K. Segment Allocations and Results The majority of our revenues and expenses are directly associated with each respective business segment and are included in determining its operating results. Those revenues and expenses that are not directly attributable to a particular business segment are allocated based on the size of each segment’s guaranty book of business. The substantial majority of the gains and losses associated with our risk management derivatives, including the impact of hedge accounting, are allocated to our Single-Family business segment. The following table displays our segment results.

Concentrations of Credit Risk

Concentrations of Credit Risk	9 Months Ended
	Sep. 30, 2022
Risks and Uncertainties [Abstract]
Concentrations of Credit Risk	Concentrations of Credit Risk Risk Characteristics of our Guaranty Book of Business One of the measures by which we gauge our credit risk is the delinquency status of the mortgage loans in our guaranty book of business. For single-family and multifamily loans, we use this information, in conjunction with housing market and other economic data, to structure our pricing and our eligibility and underwriting criteria to reflect the current risk of loans with higher-risk characteristics, and in some cases we decide to significantly reduce our participation in riskier loan product categories. Management also uses this data together with other credit risk measures to identify key trends that guide the development of our loss mitigation strategies. We report the delinquency status of our single-family and multifamily guaranty book of business below. We report loans receiving payment forbearance as delinquent according to the contractual terms of the loans. Single-Family Credit Risk Characteristics For single-family loans, management monitors the serious delinquency rate, which is the percentage of single-family loans, based on the number of loans, that are 90 days or more past due or in the foreclosure process, and loans that have higher risk characteristics, such as high mark-to-market LTV ratios. The following tables display the delinquency status and serious delinquency rates for specified loan categories of our single-family conventional guaranty book of business. As of September 30, 2022 December 31, 2021 30 Days Delinquent 60 Days Delinquent Seriously Delinquent (1) 30 Days Delinquent 60 Days Delinquent Seriously Delinquent (1) Percentage of single-family conventional guaranty book of business based on UPB 0.69 % 0.17 % 0.62 % 0.73 % 0.16 % 1.20 % Percentage of single-family conventional loans based on loan count 0.80 0.20 0.69 0.86 0.20 1.25 As of September 30, 2022 December 31, 2021 Percentage of Single-Family Conventional Guaranty Book of Business Based on UPB Serious Delinquency Rate (1) Percentage of Single-Family Conventional Guaranty Book of Business Based on UPB Serious Delinquency Rate (1) Estimated mark-to-market LTV ratio: 80.01% to 90% 4 % 0.54 % 5 % 0.88 % 90.01% to 100% 2 0.34 2 0.51 Greater than 100% * 7.42 * 12.41 Geographical distribution: California 19 0.48 19 1.01 Florida 6 0.77 6 1.59 Illinois 3 0.95 3 1.55 New Jersey 3 0.98 3 1.90 New York 5 1.28 5 2.24 All other states 64 0.66 64 1.16 Vintages: 2004 and prior 1 2.41 1 3.48 2005-2008 1 3.83 2 5.87 2009-2022 98 0.55 97 1.01 * Represents less than 0.5% of single-family conventional guaranty book of business. (1) Based on loan count, consists of single-family conventional loans that were 90 days or more past due or in the foreclosure process as of September 30, 2022 or December 31, 2021. Multifamily Credit Risk Characteristics For multifamily loans, management monitors the serious delinquency rate, which is the percentage of multifamily loans, based on unpaid principal balance, that are 60 days or more past due, and loans with other higher risk characteristics to determine the overall credit quality of our multifamily book of business. Higher risk characteristics include, but are not limited to, current debt service coverage ratio (“DSCR”) below 1.0 and original LTV ratios greater than 80%. We stratify multifamily loans into different internal risk categories based on the credit risk inherent in each individual loan. The following tables display the delinquency status and serious delinquency rates for specified loan categories of our multifamily guaranty book of business. As of September 30, 2022 (1) December 31, 2021 (1) 30 Days Delinquent Seriously Delinquent (2) 30 Days Delinquent Seriously Delinquent (2) Percentage of multifamily guaranty book of business 0.07 % 0.26 % 0.03 % 0.42 % As of September 30, 2022 December 31, 2021 Percentage of Multifamily Guaranty Book of Business (1) Serious Delinquency Rate (2)(3) Percentage of Multifamily Guaranty Book of Business (1) Serious Delinquency Rate (2)(3) Original LTV ratio: Greater than 80% 1 % 0.14 % 1 % 0.13 % Less than or equal to 80% 99 0.26 99 0.42 Current DSCR below 1.0 (4) 3 5.53 2 13.90 (1) Calculated based on the aggregate unpaid principal balance of multifamily loans for each category divided by the aggregate unpaid principal balance of loans in our multifamily guaranty book of business. (2) Consists of multifamily loans that were 60 days or more past due as of the dates indicated. (3) Calculated based on the unpaid principal balance of multifamily loans that were seriously delinquent divided by the aggregate unpaid principal balance of multifamily loans for each category included in our multifamily guaranty book of business. (4) Our estimates of current DSCRs are based on the latest available income information from annual statements for these properties. Other Concentrations Mortgage Insurers. Mortgage insurance “risk in force” refers to our maximum potential loss recovery under the applicable mortgage insurance policies in force and is generally based on the loan-level insurance coverage percentage and, if applicable, any aggregate pool loss limit, as specified in the policy. The following table displays our total mortgage insurance risk in force by primary and pool insurance, as well as the total risk-in-force mortgage insurance coverage as a percentage of the single-family conventional guaranty book of business. As of September 30, 2022 December 31, 2021 Risk in Force Percentage of Single-Family Conventional Guaranty Book of Business Risk in Force Percentage of Single-Family Conventional Guaranty Book of Business (Dollars in millions) Mortgage insurance risk in force: Primary mortgage insurance $ 189,544 $ 176,587 Pool mortgage insurance 229 261 Total mortgage insurance risk in force $ 189,773 5% $ 176,848 5% The table below displays our mortgage insurer counterparties that provided approximately 10% or more of the risk-in-force mortgage insurance coverage on mortgage loans in our single-family conventional guaranty book of business. Percentage of Risk-in-Force Coverage by Mortgage Insurer As of September 30, 2022 December 31, 2021 Counterparty: (1) Mortgage Guaranty Insurance Corp. 19 % 19 % Arch Capital Group Ltd. 19 19 Radian Guaranty, Inc. 17 17 Enact Mortgage Insurance Corp. (2) 16 17 Essent Guaranty, Inc. 16 16 National Mortgage Insurance Corp. 12 11 Others 1 1 Total 100 % 100 % (1) Insurance coverage amounts provided for each counterparty may include coverage provided by affiliates and subsidiaries of the counterparty. (2) Genworth Mortgage Insurance Corp. was renamed Enact Mortgage Insurance Corp. effective February 7, 2022. We have counterparty credit risk relating to the potential insolvency of, or non-performance by, monoline mortgage insurers that insure single-family loans we purchase or guarantee. There is risk that these counterparties may fail to fulfill their obligations to pay our claims under insurance policies. On at least a quarterly basis, we assess our mortgage insurer counterparties’ respective abilities to fulfill their obligations to us. Our assessment includes financial reviews and analyses of the insurers’ portfolios and capital adequacy. If we determine that it is probable that we will not collect all of our claims from one or more of our mortgage insurer counterparties, it could increase our loss reserves, which could adversely affect our results of operations, liquidity, financial condition and net worth. When we estimate the credit losses that are inherent in our mortgage loans and under the terms of our guaranty obligations, we also consider the recoveries that we expect to receive from primary mortgage insurance, as mortgage insurance recoveries reduce the severity of the loss associated with defaulted loans if the borrower defaults and title to the property is subsequently transferred. Mortgage insurance does not cover credit losses that result from a reduction in mortgage interest paid by the borrower in connection with a loan modification, forbearance of principal, or forbearance of scheduled loan payments. We evaluate the financial condition of our mortgage insurer counterparties and adjust the contractually due recovery amounts to ensure that expected credit losses as of the balance sheet date are included in our loss reserve estimate. As a result, if our assessment of one or more of our mortgage insurer counterparties’ ability to fulfill their respective obligations to us worsens, it could increase our loss reserves. As of September 30, 2022 and December 31, 2021, our estimated benefit from mortgage insurance, which is based on estimated credit losses as of period end, reduced our loss reserves by $1.5 billion and $559 million, respectively. As of September 30, 2022 and December 31, 2021, we had outstanding receivables of $517 million and $533 million, respectively, recorded in “Other assets” in our condensed consolidated balance sheets related to amounts claimed on insured, defaulted loans excluding government-insured loans. As of September 30, 2022 and December 31, 2021, we assessed these outstanding receivables for collectability, and established a valuation allowance of $463 million and $479 million, respectively. Mortgage Servicers and Sellers. Mortgage servicers collect mortgage and escrow payments from borrowers, pay taxes and insurance costs from escrow accounts, monitor and report delinquencies, and perform other required activities, including loss mitigation, on our behalf. Our mortgage servicers and sellers may also be obligated to repurchase loans or real estate owned (“REO”) properties, reimburse us for losses or provide other remedies under certain circumstances, such as if it is determined that the mortgage loan did not meet our underwriting or eligibility requirements, if certain loan representations and warranties are violated or if mortgage insurers rescind coverage. Our representation and warranty framework does not require repurchase for loans that have breaches of certain selling representations and warranties if they have met specified criteria for relief. Our business with mortgage servicers is concentrated. The table below displays the percentage of our single-family guaranty book of business serviced by our top five depository single-family mortgage servicers and top five non-depository single-family mortgage servicers (i.e., servicers that are not insured depository institutions), and identifies one servicer that serviced 10% or more of our single-family guaranty book of business as of December 31, 2021, based on unpaid principal balance. Percentage of Single-Family As of September 30, 2022 December 31, 2021 Wells Fargo Bank, N.A. (together with its affiliates) 9 % 10 % Remaining top five depository servicers 12 11 Top five non-depository servicers 23 23 Total 44 % 44 % Compared with depository financial institutions, our non-depository servicers pose additional risks because they may not have the same financial strength or operational capacity, or be subject to the same level of regulatory oversight as depository financial institutions. The table below displays the percentage of our multifamily guaranty book of business serviced by our top five multifamily mortgage servicers, and identifies two servicers that serviced 10% or more of our multifamily guaranty book of business based on unpaid principal balance. Percentage of Multifamily As of September 30, 2022 December 31, 2021 Walker & Dunlop, LLC 13 % 12 % Wells Fargo Bank, N.A. (together with its affiliates) 11 11 Remaining top five servicers 24 24 Total 48 % 47 % If a significant mortgage servicer or seller counterparty, or a number of mortgage servicers or sellers, fails to meet their obligations to us, it could adversely affect our results of operations and financial condition. We mitigate these risks in several ways, including: • establishing minimum standards and financial requirements for our servicers; • monitoring financial and portfolio performance as compared with peers and internal benchmarks; and • for our largest mortgage servicers, conducting periodic financial reviews to confirm compliance with servicing guidelines and servicing performance expectations. We may take one or more of the following actions to mitigate our credit exposure to mortgage servicers that present a higher risk: • require a guaranty of obligations by higher-rated entities; • transfer exposure to third parties; • require collateral; • establish more stringent financial requirements; • work with underperforming servicers to improve operational processes; and • suspend or terminate the selling and servicing relationship if deemed necessary. Derivatives Counterparties.

Offsetting [Abstract]
Netting Arrangements	Netting Arrangements We use master netting arrangements, which allow us to offset certain financial instruments and collateral with the same counterparty, to minimize counterparty credit exposure. The tables below display information related to derivatives, securities purchased under agreements to resell, and securities sold under agreements to repurchase, which are subject to an enforceable master netting arrangement or similar agreement that are either offset or not offset in our condensed consolidated balance sheets.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value We use fair value measurements for the initial recording of certain assets and liabilities and periodic remeasurement of certain assets and liabilities on a recurring or nonrecurring basis. Fair Value Measurement Fair value measurement guidance defines fair value, establishes a framework for measuring fair value, and sets forth disclosures around fair value measurements. This guidance applies whenever other accounting guidance requires or permits assets or liabilities to be measured at fair value. The guidance establishes a three-level fair value hierarchy that prioritizes the inputs into the valuation techniques used to measure fair value. The hierarchy gives the highest priority, Level 1, to measurements based on unadjusted quoted prices in active markets for identical assets or liabilities. The next highest priority, Level 2, is given to measurements of assets and liabilities based on limited observable inputs or observable inputs for similar assets and liabilities. The lowest priority, Level 3, is given to measurements based on unobservable inputs. We use valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. See “Note 15, Fair Value” in our 2021 Form 10-K for information on the valuation control processes and the valuation techniques we use for fair value measurement and disclosure as well as our basis for classifying these measurements as Level 1, Level 2 or Level 3 of the valuation hierarchy in more specific situations. If the inputs used to measure assets or liabilities at fair value change, it may also result in a change in classification between levels 1, 2, and 3. We made no material changes to the valuation control processes or the valuation techniques for the nine months ended September 30, 2022. Recurring Changes in Fair Value The following tables display our assets and liabilities measured in our condensed consolidated balance sheets at fair value on a recurring basis subsequent to initial recognition, including instruments for which we have elected the fair value option.

The following tables display valuation techniques and the range and the weighted average of significant unobservable inputs for our Level 3 assets and liabilities measured at fair value on a recurring basis, excluding instruments for which we have elected the fair value option. Changes in these unobservable inputs can result in significantly higher or lower fair value measurements of these assets and liabilities as of the reporting date.

Where we have disclosed unobservable inputs for consensus and single vendor techniques, those inputs are based on our validations performed at the security level using discounted cash flows. (2) Unobservable inputs were weighted by the relative fair value of the instruments. (3) Includes Fannie Mae and Freddie Mac securities. In our condensed consolidated balance sheets, certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when we evaluate loans for impairment). We had no Level 1 assets or liabilities that were measured at fair value on a nonrecurring basis as of September 30, 2022 or December 31, 2021. We held $282 million and $38 million in Level 2 assets as of September 30, 2022 and December 31, 2021, respectively, composed of mortgage loans held for sale that were impaired. We had no Level 2 or Level 3 liabilities that were measured at fair value on a nonrecurring basis as of September 30, 2022 or December 31, 2021. The following table displays valuation techniques for our Level 3 assets measured at fair value on a nonrecurring basis.

Fair Value of Financial Instruments The following table displays the carrying value and estimated fair value of our financial instruments. The fair value of financial instruments we disclose includes commitments to purchase multifamily and single-family mortgage loans that we do not record in our condensed consolidated balance sheets. The fair values of these commitments are included as “Mortgage loans held for investment, net of allowance for loan losses.” The disclosure excludes all non-financial instruments; therefore, the fair value of our financial assets and liabilities does not represent the underlying fair value of our total consolidated assets and liabilities.

Fair Value Option We elected the fair value option for loans and debt that contain embedded derivatives that would otherwise require bifurcation. Under the fair value option, we elected to carry these instruments at fair value instead of bifurcating the embedded derivative from such instruments. Interest income for the mortgage loans is recorded in “Interest income: Mortgage loans” and interest expense for the debt instruments is recorded in “Interest expense: Long-term debt” in our condensed consolidated statements of operations and comprehensive income. The following table displays the fair value and unpaid principal balance of the financial instruments for which we have made fair value elections. As of September 30, 2022 December 31, 2021 Loans (1) Long-Term Debt of Fannie Mae Long-Term Debt of Consolidated Trusts Loans (1) Long-Term Debt of Fannie Mae Long-Term Debt of Consolidated Trusts (Dollars in millions) Fair value $ 3,691 $ 1,766 $ 16,758 $ 4,964 $ 2,381 $ 21,735 Unpaid principal balance 3,956 1,732 16,906 4,601 2,197 19,314 (1) Includes nonaccrual loans with a fair value of $44 million and $86 million as of September 30, 2022 and December 31, 2021, respectively. Includes loans that are 90 days or more past due with a fair value of $53 million and $125 million as of September 30, 2022 and December 31, 2021, respectively. Changes in Fair Value under the Fair Value Option Election We recorded losses of $209 million and $587 million for the three and nine months ended September 30, 2022 and gains of $28 million and $48 million for the three and nine months ended September 30, 2021 from changes in the fair value of loans recorded at fair value in “Fair value gains (losses), net” in our condensed consolidated statements of operations and comprehensive income. We recorded gains of $787 million and $2.4 billion for the three and nine months ended September 30, 2022 and gains of $62 million and $346 million for the three and nine months ended September 30, 2021, respectively, from changes in the fair value of long-term debt recorded at fair value in “Fair value gains (losses), net” in our condensed consolidated statements of operations and comprehensive income.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies We are party to various types of legal actions and proceedings, including actions brought on behalf of various classes of claimants. We also are subject to regulatory examinations, inquiries and investigations, and other information gathering requests. In some of the matters, indeterminate amounts are sought. Modern pleading practice in the U.S. permits considerable variation in the assertion of monetary damages or other relief. Jurisdictions may permit claimants not to specify the monetary damages sought or may permit claimants to state only that the amount sought is sufficient to invoke the jurisdiction of the trial court. This variability in pleadings, together with our and our counsel’s actual experience in litigating or settling claims, leads us to conclude that the monetary relief that may be sought by plaintiffs bears little relevance to the merits or disposition value of claims. We have substantial and valid defenses to the claims in the proceedings described below and intend to defend these matters vigorously. However, legal actions and proceedings of all types are subject to many uncertain factors that generally cannot be predicted with assurance. Accordingly, the outcome of any given matter and the amount or range of potential loss at particular points in time is frequently difficult to ascertain. Uncertainties can include how fact finders will evaluate documentary evidence and the credibility and effectiveness of witness testimony, and how the court will apply the law. Disposition valuations are also subject to the uncertainty of how opposing parties and their counsel may view the evidence and applicable law. On a quarterly basis, we review relevant information about all pending legal actions and proceedings for the purpose of evaluating and revising our contingencies, accruals and disclosures. We establish an accrual only for matters when the likelihood of a loss is probable and we can reasonably estimate the amount of such loss. We are often unable to estimate the possible losses or ranges of losses, particularly for proceedings that are in their early stages of development, where plaintiffs seek indeterminate or unspecified damages, where there may be novel or unsettled legal questions relevant to the proceedings, or where settlement negotiations have not occurred or progressed. Given the uncertainties involved in any action or proceeding, regardless of whether we have established an accrual, the ultimate resolution of certain of these matters may be material to our operating results for a particular period, depending on, among other factors, the size of the loss or liability imposed and the level of our net income or loss for that period. In addition to the matters specifically described below, we are involved in a number of legal and regulatory proceedings that arise in the ordinary course of business that we do not expect will have a material impact on our business or financial condition. Senior Preferred Stock Purchase Agreements Litigation A consolidated class action ( “In re Fannie Mae/Freddie Mac Senior Preferred Stock Purchase Agreement Class Action Litigations” ) and a non-class action lawsuit, Fairholme Funds v. FHFA , filed by Fannie Mae and Freddie Mac shareholders against us, FHFA as our conservator, and Freddie Mac are pending in the U.S. District Court for the District of Columbia. The lawsuits challenge the August 2012 amendment to each company’s senior preferred stock purchase agreement with Treasury. Plaintiffs in these lawsuits allege that the net worth sweep dividend provisions of the senior preferred stock that were implemented pursuant to the August 2012 amendments nullified certain of the shareholders’ rights and caused them harm. Plaintiffs in the class action represent a class of Fannie Mae preferred shareholders and classes of Freddie Mac common and preferred shareholders. On September 23, 2022, the court issued a summary judgment ruling that permitted the plaintiffs in these lawsuits to present to a jury their claims for breach of the implied covenant of good faith and fair dealing. The cases were consolidated for trial and the trial was conducted from October 17, 2022 to November 1, 2022. Jury deliberations began on November 1, 2022. The jury in this trial was not able to reach a verdict and the judge declared a mistrial on November 7, 2022. We expect the court to set a new trial date. In the trial, plaintiffs requested $779 million in damages from Fannie Mae and prejudgment interest on the amount of any damages. We estimate that prejudgment interest, if awarded, would be calculated at a rate of 5.75% and expect plaintiffs to seek such interest from August 17, 2012. Prejudgment interest calculated from August 17, 2012 through September 30, 2022 based on the amount of damages plaintiffs requested would be approximately $450 million. The ultimate amount of prejudgment interest awarded, if any, would be impacted by the amount of damages awarded, the date from and through which interest is calculated, and other determinations by the court. At this time, we do not believe the likelihood of loss is probable; therefore, we have not established an accrual in connection with these lawsuits. However, it is reasonably possible that the plaintiffs could ultimately prevail in this matter and, if so, we may incur a loss up to the amount of damages discussed above and any related interest.

Regulatory Capital Requirements

Regulatory Capital Requirements	9 Months Ended

Broker-Dealer, Net Capital Requirement, SEC Regulation [Abstract]
Regulatory Capital Requirements	Regulatory Capital Requirements FHFA published a final rule establishing a new enterprise regulatory capital framework for the GSEs in December 2020. FHFA published a final rule amending the enterprise regulatory capital framework in March 2022. We refer to the rule’s requirements, as amended, as the “enterprise regulatory capital framework.” The enterprise regulatory capital framework establishes new supplemental leverage and risk-based capital requirements for the GSEs. Under the leverage capital requirements, we must maintain a tier 1 capital ratio of 2.5% of adjusted total assets. Under the risk-based capital requirements, we must maintain minimum common equity tier 1 capital, tier 1 capital, and adjusted total capital ratios of 4.5%, 6%, and 8%, respectively, of risk-weighted assets. The enterprise regulatory capital framework requires substantially higher levels of capital than the previously applicable statutory minimum capital requirement. Although the enterprise regulatory capital framework went into effect in February 2021, we are not required to hold capital according to the framework’s requirements until the date of termination of our conservatorship, or such later date as may be ordered by FHFA. The enterprise regulatory capital framework provides a granular assessment of credit risk specific to different mortgage loan categories, as well as components for market risk and operational risk. The enterprise regulatory capital framework includes the following requirements: • Supplemental capital requirements relating to the amount and form of the capital we hold, based largely on definitions of capital used in U.S. banking regulators’ regulatory capital framework. The enterprise regulatory capital framework specifies complementary leverage and risk-based requirements, which together determine the requirements for each tier of capital; • A requirement that we hold prescribed capital buffers that can be drawn down in periods of financial stress and then rebuilt over time as economic conditions improve. If we fall below the prescribed buffer amounts, we must restrict capital distributions such as stock repurchases and dividends, as well as discretionary bonus payments to executives, until the buffer amounts are restored. The prescribed capital buffers represent the amount of capital we are required to hold above the minimum leverage and risk-based capital requirements. ◦ The prescribed leverage buffer amount (“PLBA”) represents the amount of tier 1 capital we are required to hold above the minimum tier 1 leverage capital requirement; ◦ The risk-based capital buffers consist of three separate components: a stability capital buffer, a stress capital buffer, and a countercyclical capital buffer. Taken together, these risk-based buffers comprise the prescribed capital conservation buffer amount (“PCCBA”). The PCCBA must be comprised entirely of common equity tier 1 capital; and • Specific minimum percentages, or “floors,” on the risk-weights applicable to single-family and multifamily exposures, as well as retained portions of credit risk transfer transactions. The table below sets forth information about our capital requirements under the standardized approach of the enterprise regulatory capital framework. Available capital for purposes of the enterprise regulatory capital framework excludes the stated value of the senior preferred stock ($120.8 billion) and other amounts specified in footnote 2 to the table. Because of these exclusions, we had a deficit in available capital as of September 30, 2022, even though we had positive net worth under GAAP of $58.8 billion as of September 30, 2022. As of September 30, 2022, we had a $258 billion shortfall of our available capital (deficit) to the adjusted total capital requirement (including buffers) of $183 billion under the standardized approach of the rule as shown in the table below. As of September 30, 2022, our risk-based adjusted total capital requirement (including buffers) represented the amount of capital needed to be fully capitalized under the standardized approach to the rule. Capital Metrics under the Enterprise Regulatory Capital Framework as of September 30, 2022 (1) (Dollars in billions) Adjusted total assets $ 4,540 Risk-weighted assets 1,298 Amounts Ratios Available Capital (Deficit) (2) Minimum Capital Requirement Total Capital Requirement (including Buffers) (4) Available Capital (Deficit) Ratio (3) Minimum Capital Ratio Requirement Total Capital Requirement Ratio (including Buffers) Risk-based capital: Total capital (5) $ (53) $ 104 $ 104 (4.1) % 8.0 % 8.0 % Common equity tier 1 capital (94) 58 137 (7.2) 4.5 10.6 Tier 1 capital (75) 78 157 (5.8) 6.0 12.1 Adjusted total capital (75) 104 183 (5.8) 8.0 14.1 Leverage capital: Core capital (6) (62) 113 113 (1.4) 2.5 2.5 Tier 1 capital (75) 113 136 (1.7) 2.5 3.0 (1) Ratios are calculated as a percentage of risk-weighted assets for risk-based capital metrics and as a percentage of adjusted total assets for leverage capital metrics. (2) Available capital (deficit) for all line items excludes the stated value of the senior preferred stock ($120.8 billion). Available capital (deficit) for all line items except total capital and core capital also deducts a portion of deferred tax assets. Deferred tax assets arising from temporary differences between GAAP and tax requirements are deducted from capital to the extent they exceed 10% of common equity. As of September 30, 2022, this resulted in the full deduction of deferred tax assets ($12.7 billion) from our available capital (deficit). Available capital (deficit) for common equity tier 1 capital also excludes the value of the non-cumulative perpetual preferred stock ($19.1 billion). (3) Ratios are negative because we had a deficit in available capital for each tier of capital. (4) The applicable buffer for common equity tier 1 capital, tier 1 capital, and adjusted total capital is the PCCBA, comprised of a stress capital buffer, a stability capital buffer, and a countercyclical capital buffer. The applicable buffer for tier 1 capital (leverage based) is the PLBA. The stress capital buffer and countercyclical capital buffer are each calculated by multiplying prescribed factors by adjusted total assets as of the last day of the previous calendar quarter. The 2022 stability capital buffer is calculated by multiplying a factor determined based on our share of mortgage debt outstanding by adjusted total assets as of December 31, 2020. The prescribed leverage buffer for 2022 is set at 50% of the 2022 stability buffer. Going forward the stability buffer and the prescribed leverage buffer will be updated with an effective date that depends on whether the stability capital buffer increases or decreases relative to the previously calculated value. (5) The sum of (a) core capital (see definition in footnote 6 below); and (b) a general allowance for foreclosure losses, which (i) shall include an allowance for portfolio mortgage losses, an allowance for non-reimbursable foreclosure costs on government claims, and an allowance for liabilities reflected on the balance sheet for estimated foreclosure losses on mortgage-backed securities; and (ii) shall not include any reserves made or held against specific assets; and (c) any other amounts from sources of funds available to absorb losses that the Director of FHFA by regulation determines are appropriate to include in determining total capital. (6) The sum of (a) the stated value of our outstanding common stock (common stock less treasury stock); (b) the stated value of our outstanding non-cumulative perpetual preferred stock; (c) our paid-in capital; and (d) our retained earnings (accumulated deficit). Core capital does not include: (a) accumulated other comprehensive income or (b) senior preferred stock.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and with the SEC’s instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and note disclosures required by GAAP for complete consolidated financial statements. In the opinion of management, all adjustments of a normal recurring nature considered necessary for a fair presentation have been included. The accompanying condensed consolidated financial statements include our accounts as well as the accounts of other entities in which we have a controlling financial interest. All intercompany accounts and transactions have been eliminated.
Use of Estimates	Use of Estimates Preparing condensed consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect our reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the dates of our condensed consolidated financial statements, as well as our reported amounts of revenues and expenses during the reporting periods. Management has made significant estimates in a variety of areas including, but not limited to, the allowance for loan losses. Actual results could be different from these estimates.
Conservatorship	Conservatorship On September 7, 2008, the Secretary of the Treasury and the Director of FHFA announced several actions taken by Treasury and FHFA regarding Fannie Mae, which included: (1) placing us in conservatorship, with FHFA acting as our conservator, and (2) the execution of a senior preferred stock purchase agreement by our conservator, on our behalf, and Treasury, pursuant to which we issued to Treasury both senior preferred stock and a warrant to purchase common stock. Under the Federal Housing Enterprises Financial Safety and Soundness Act of 1992, as amended, including by the Housing and Economic Recovery Act of 2008 (together, the “GSE Act”), the conservator immediately succeeded to (1) all rights, titles, powers and privileges of Fannie Mae, and of any stockholder, officer or director of Fannie Mae with respect to Fannie Mae and its assets, and (2) title to the books, records and assets of any other legal custodian of Fannie Mae. The conservator subsequently issued an order that provided for our Board of Directors to exercise specified functions and authorities. The conservator also provided instructions regarding matters for which conservator decision or notification is required. The conservator retains the authority to amend or withdraw its order and instructions at any time. The conservatorship has no specified termination date and there continues to be significant uncertainty regarding our future, including how long we will continue to exist in our current form, the extent of our role in the market, the level of government support of our business, how long we will be in conservatorship, what form we will have and what ownership interest, if any, our current common and preferred stockholders will hold in us after the conservatorship is terminated and whether we will continue to exist following conservatorship. Under the GSE Act, the Director of FHFA must place us into receivership if they make a written determination that our assets are less than our obligations or if we have not been paying our debts, in either case, for a period of 60 days. In addition, the Director of FHFA may place us into receivership at the Director’s discretion at any time for other reasons set forth in the GSE Act, including if we are critically undercapitalized or if we are undercapitalized and have no reasonable prospect of becoming adequately capitalized. Should we be placed into receivership, different assumptions would be required to determine the carrying value of our assets, which would lead to substantially different financial results. Treasury has made a commitment under the senior preferred stock purchase agreement to provide funding to us under certain circumstances if we have a net worth deficit. We are not aware of any plans of FHFA (1) to fundamentally change our business model, or (2) to reduce the aggregate amount available to or held by the company under our equity structure, which includes the senior preferred stock purchase agreement.
Related Parties	Related Parties Because Treasury holds a warrant to purchase shares of Fannie Mae common stock equal to 79.9% of the total number of shares of Fannie Mae common stock, we and Treasury are deemed related parties. FHFA’s control of both Fannie Mae and Freddie Mac has caused Fannie Mae, FHFA and Freddie Mac to be deemed related parties. Additionally, Fannie Mae and Freddie Mac jointly own Common Securitization Solutions, LLC (“CSS”), a limited liability company created to operate a common securitization platform; as a result, CSS is deemed a related party. As a part of our joint ownership, Fannie Mae, Freddie Mac and CSS are parties to a limited liability company agreement that sets forth the overall framework for the joint venture, including Fannie Mae’s and Freddie Mac’s rights and responsibilities as members of CSS. Fannie Mae, Freddie Mac and CSS are also parties to a customer services agreement that sets forth the terms under which CSS provides mortgage securitization services to us and Freddie Mac, including the operation of the common securitization platform, as well as an administrative services agreement. CSS operates as a separate company from us and Freddie Mac, with all funding and limited administrative support services and other resources provided to it by us and Freddie Mac. In the ordinary course of business, Fannie Mae may purchase and sell securities issued by Treasury and Freddie Mac. These transactions occur on the same terms as those prevailing at the time for comparable transactions with unrelated parties. Some of the structured securities we issue are backed in whole or in part by Freddie Mac securities. Fannie Mae and Freddie Mac each have agreed to indemnify the other party for losses caused by: its failure to meet its payment or other specified obligations under the trust agreements pursuant to which the underlying resecuritized securities were issued; its failure to meet its obligations under the customer services agreement; its violations of laws; or with respect to material misstatements or omissions in offering documents, ongoing disclosures and related materials
Single-Family Guaranty Fees 10 Basis Points Increase due to a provision stated in the Temporary Payroll Tax Cut Continuation Act of 2011	To meet our obligations under the TCCA and at the direction of FHFA, we increased the guaranty fee on all single-family residential mortgages delivered to us by 10 basis points effective April 1, 2012. The resulting fee revenue and expense are recorded in “Interest income: Mortgage loans” and “TCCA fees,” respectively, in our condensed consolidated statements of operations and comprehensive income. In November 2021, the Infrastructure Investment and Jobs Act was enacted, which extended to October 1, 2032 our obligation under the TCCA to collect 10 basis points in guaranty fees on single-family residential mortgages delivered to us and pay the associated revenue to Treasury. In January 2022, FHFA advised us to continue to pay these TCCA fees to Treasury with respect to all single-family loans acquired by us before October 1, 2032, and to continue to remit these amounts to Treasury on and after October 1, 2032 with respect to loans we acquired before this date until those loans are paid off or otherwise liquidated.
Earnings per Share	Earnings per Share Earnings per share (“EPS”) is presented for basic and diluted EPS. We compute basic EPS by dividing net income attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. However, as a result of our conservatorship status and the terms of the senior preferred stock, no amounts would be available to distribute as dividends to common or preferred stockholders (other than to Treasury as the holder of the senior preferred stock). Net income attributable to common stockholders excludes amounts attributable to the senior preferred stock.
New Accounting Pronouncements	New Accounting Guidance Adoption of ASU 2022-02 The Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2022-02, Financial Instruments – Credit Losses (Topic 326) Troubled Debt Restructurings and Vintage Disclosures (“ASU 2022-02”) in March 2022. The amendments in ASU 2022-02 eliminate the accounting guidance for troubled debt restructurings (“TDRs”) by creditors while enhancing disclosure requirements for certain loan restructurings by creditors when a borrower is experiencing financial difficulty. Specifically, rather than applying the recognition and measurement guidance for TDRs, an entity would apply the loan refinancing and restructuring guidance to determine whether a modification or other form of restructuring results in a new loan or a continuation of an existing loan. Additionally, the amendments in this ASU require that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases in the existing vintage disclosures. The ASU is effective for fiscal years beginning after December 15, 2022, for creditors that have adopted the amendments in Accounting Standards Update 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. Early adoption is permitted in any interim period and such election may be made individually to adopt the guidance related to TDRs, including related disclosures, and the presentation of gross write-offs in the vintage disclosures. ASU 2022-02 requires prospective transition for the disclosures related to loan restructurings for borrowers experiencing financial difficulty and the presentation of gross write-offs in the vintage disclosures. The guidance related to the recognition and measurement of TDRs may be adopted on a prospective or modified retrospective transition method. We elected to early adopt the guidance related to the elimination of the recognition and measurement of TDRs and the enhancement of disclosures for loan restructurings for borrowers experiencing financial difficulty as of January 1, 2022, using the prospective transition method. As of our adoption date, all restructurings, including restructurings for borrowers experiencing financial difficulty, are evaluated to determine whether they result in a new loan or a continuation of an existing loan. Loan restructurings for borrowers experiencing financial difficulty are generally accounted for as a continuation of the existing loan as the terms of the restructured loans are typically not at market rates. At adoption of this guidance on January 1, 2022, there was no material impact on our financial statements. When a single-family loan is restructured under ASU 2022-02, we continue to measure impairment on the loan using a discounted cash flow approach that utilizes a prepayment-adjusted discount rate that is based on the loan’s restructured terms. Under the TDR accounting model, we used the discount rate that was in effect prior to the restructuring to measure impairment. Using the interest rate that was in effect prior to the restructuring resulted in the recognition, in the allowance for loan losses, of the economic concession that we granted to borrowers as part of the loan restructuring. Using a post-restructuring interest rate does not result in the recognition of an economic concession in the allowance for loan losses. As we have elected a prospective transition, the economic concession on a loan that was previously restructured and accounted for as a TDR will continue to be measured in our allowance for loan losses using the discount rate that was in effect prior to the restructuring and the economic concession may increase or decrease as we update our cash flow assumptions related to the loan’s expected life. Further, the component of the allowance for loan losses representing economic concessions will decrease as the borrower makes payments in accordance with the restructured terms of the mortgage loan and as the loan is sold, liquidated, or subsequently restructured. In general, the accounting for restructurings made to borrowers experiencing financial difficulty upon adoption of the ASU is consistent with the accounting that we applied to troubled debt restructurings under section 4013 of the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), and the Consolidated Appropriations Act of 2021, which provided temporary relief from the accounting and reporting requirements for certain troubled debt restructurings related to COVID-19 beginning March 2020 through January 1, 2022. We plan to adopt the disclosure guidance related to the presentation of gross write-offs by year of origination in our vintage disclosures upon the effective date of ASU 2022-02, January 1, 2023. We do not expect the adoption of the guidance requiring gross write-offs by year of origination in our vintage disclosures to have a material impact on our financial statements. Fair Value Hedging - Portfolio Layer Method On March 28, 2022, the FASB issued ASU 2022-01, Fair Value Hedging - Portfolio Layer Method, which clarifies the guidance on fair value hedge accounting of interest rate risk portfolios of financial assets. The ASU expands the scope of the current last-of-layer method to allow entities to apply this method, renamed the portfolio layer method, to non-prepayable financial assets and to designate multiple hedge relationships within a single closed portfolio of financial assets. Additionally, the ASU clarifies that basis adjustments related to existing portfolio layer hedge relationships should not be considered when measuring credit losses on the financial assets included in the closed portfolio. Further, the ASU clarifies that any reversal of fair value hedge basis adjustments associated with an actual breach should be recognized in interest income immediately. The ASU is effective for public business entities for fiscal years beginning after December 15, 2022, and interim periods within those years. We plan to adopt this guidance effective January 1, 2023. The adoption of this guidance is not expected to have a material impact on our financial statements.
Consolidations	We have interests in various entities that are considered to be variable interest entities (“VIEs”). The primary types of entities are securitization and resecuritization trusts, limited partnerships and special purpose vehicles (“SPVs”). These interests include investments in securities issued by VIEs, such as Fannie Mae MBS created pursuant to our securitization transactions and our guaranty to the entity. We consolidate the substantial majority of our single-class securitization trusts because our role as guarantor and master servicer provides us with the power to direct matters (primarily the servicing of mortgage loans) that impact the credit risk to which we are exposed. In contrast, we do not consolidate single-class securitization trusts when other organizations have the power to direct these activities unless we have the unilateral ability to dissolve the trust. We also do not consolidate our resecuritization trusts unless we have the unilateral ability to dissolve the trust. The underlying assets of our resecuritization trusts include both Fannie Mae securities collateralized solely by mortgage loans held in consolidated trusts as well as uniform mortgage-backed securities (“UMBS ® ”) collateralized with securities issued by Fannie Mae or Freddie Mac. The mortgage loans that serve as collateral for Freddie Mac-issued securities are not held in trusts that are consolidated by Fannie Mae.
Transfers of Financial Assets	Transfers of Financial AssetsWe issue Fannie Mae MBS through portfolio securitization transactions by transferring pools of mortgage loans or mortgage-related securities to one or more trusts or special purpose entities. We are considered to be the transferor when we transfer assets from our own retained mortgage portfolio in a portfolio securitization transaction.We retain interests from the transfer and sale of mortgage-related securities to unconsolidated single-class and multi-class portfolio securitization trusts.
Mortgage Loans Held-for-investment	we report the amortized cost of HFI loans for which we have not elected the fair value option at the unpaid principal balance, net of unamortized premiums and discounts, hedge-related basis adjustments, other cost basis adjustments, and accrued interest receivable in these “Note 3, Mortgage Loans” disclosures. For purposes of our condensed consolidated balance sheets, we present accrued interest receivable, net separately from the amortized cost of our loans held for investment.
Mortgage Loans Held-for-sale	We report the carrying value of HFS loans at the lower of cost or fair value and record valuation changes in “Investment gains (losses), net” in our condensed consolidated statements of operations and comprehensive income.
Nonaccrual Loans and Allowance for Loan Losses	The estimated mark-to-market loan-to-value (“LTV”) ratio is a primary factor we consider when estimating our allowance for loan losses for single-family loans. As LTV ratios increase, the borrower's equity in the home decreases, which may negatively affect the borrower's ability to refinance or to sell the property for an amount at or above the outstanding balance of the loan.Property rental income and property valuations are key inputs to our internally assigned credit risk ratings. Nonaccrual Loans For loans negatively impacted by the COVID-19 pandemic, we continue to recognize interest income for up to six months of delinquency provided that the loan was either current as of March 1, 2020 or originated after March 1, 2020. For single-family loans, we continue to accrue interest income beyond six months of delinquency provided that the collection of principal and interest continues to be reasonably assured. Multifamily loans that are in a forbearance arrangement are placed on nonaccrual status when the borrower is six months past due unless the loan is both well secured and in the process of collection. For single-family and multifamily loans in a forbearance arrangement that are placed on nonaccrual status, cash payments for interest are applied as a reduction of accrued interest receivable until the receivable has been reduced to zero, and then recognized as interest income. For loans that have been negatively impacted by COVID-19, we establish a valuation allowance for expected credit losses on the accrued interest receivable balance applying the process that we have established for both single-family and multifamily loans. The credit expense related to this valuation allowance is classified as a component of the provision for credit losses. Accrued interest receivable is written off when the amount is deemed to be uncollectible. Loans that are in active forbearance plans are not evaluated for write-off. For loans not subject to the COVID-19-related guidance, we have elected not to measure an allowance for credit losses on accrued interest receivable balances as we have a nonaccrual policy to ensure the timely reversal of unpaid accrued interest. See “Note 4, Allowance for Loan Losses” for additional information about our current-period provision for loan losses. For loans not subject to the COVID-19-related nonaccrual policy we discontinue accruing interest when we believe collectability of principal and interest is not reasonably assured, which for a single-family loan we have determined, based on our historical experience, to be when the loan becomes two months or more past due according to its contractual terms. Single-family and multifamily loans are reported past due if a full payment of principal and interest is not received within one month of its due date. Interest income previously accrued but not collected is reversed through interest income at the date the loan is placed on nonaccrual status. For single-family loans on nonaccrual status, we recognize income when cash payments are received. We return a non-modified single-family loan to accrual status at the point when the borrower brings the loan current. As a part of our single-family loss mitigation activities, we restructure loans where the borrower is experiencing financial difficulty. For the purpose of income recognition, we require the borrower to complete a performance period for those loss mitigation arrangements that bring the loan current via the capitalization of the past due principal and interest (i.e., contractual modifications and payment deferrals). In that regard, our contractual modifications generally include a trial period (a performance period of generally 3 to 4 months) that the borrower has to complete before the loan is permanently modified. The loans that receive these contractual modifications are not returned to accrual status until the borrower has successfully made all required payments during the trial period and the modification is made permanent. As payment deferrals do not include a trial period, these restructurings are not returned to accrual status until the borrower has made three consecutive contractual payments. If interest is capitalized pursuant to either a loan modification or a payment deferral, any capitalized interest that had not been previously recognized as interest income is recorded as a discount to the loan and amortized over the life of the loan. For loans that have not been negatively impacted by COVID-19, we place a multifamily loan on nonaccrual status when the loan becomes two months or more past due according to its contractual terms unless the loan is well secured such that collectability of principal and accrued interest is reasonably assured. For multifamily loans on nonaccrual status, we apply any payment received on a cost recovery basis to reduce principal on the mortgage loan. We return a multifamily loan to accrual status when the borrower cures the delinquency of the loan. Our benefit or provision for loan losses can vary substantially from period to period based on a number of factors, such as changes in actual and forecasted home prices or property valuations, fluctuations in actual and forecasted interest rates, borrower payment behavior, events such as natural disasters or pandemics, the type, volume and effectiveness of our loss mitigation activities, including forbearances and loan modifications, the volume of foreclosures completed, and the volume and pricing of loans redesignated from HFI to HFS. Our benefit or provision can also be impacted by updates to the models, assumptions, and data used in determining our allowance for loan losses. In recent periods, changes in actual and projected interest rates have been a meaningful driver of our benefit or provision for loan losses as these changes drive prepayment speeds and impact the measurement of the economic concessions granted to borrowers on modified loans. Pursuant to our adoption of ASU 2022-02 on January 1, 2022, we prospectively discontinued TDR accounting and no longer measure the economic concession for restructurings occurring on or after the adoption date. This accounting also results in the elimination of any existing economic concession related to a loan that was previously designated as a TDR if such loan is restructured on or after January 1, 2022. See “Note 1, Summary of Significant Accounting Policies—New Accounting Guidance” for more information about our adoption of ASU 2022-02.
Trading and Available-for-sale Securities	Trading SecuritiesTrading securities are recorded at fair value with subsequent changes in fair value recorded in “Fair value gains (losses), net” in our condensed consolidated statements of operations and comprehensive income. Available-for-Sale Securities We record AFS securities at fair value with unrealized gains and losses, recorded net of tax, as a component of “Other comprehensive loss” and we recognize realized gains and losses from the sale of AFS securities in “Investment gains (losses), net” in our condensed consolidated statements of operations and comprehensive income. We define the amortized cost basis of our AFS securities as unpaid principal balance, net of unamortized premiums and discounts, and other cost basis adjustments. We record an allowance for credit losses for AFS securities that reflects the impairment for credit losses, which are limited to the amount that fair value is less than the amortized cost. Impairment due to non-credit losses are recorded as unrealized losses within “Other comprehensive loss.”
Financial Guarantees	We recognize a guaranty obligation for our obligation to stand ready to perform on our guarantees to unconsolidated trusts and other guaranty arrangements. These off-balance sheet guarantees expose us to credit losses primarily relating to the unpaid principal balance of our unconsolidated Fannie Mae MBS and other financial guarantees.We measure our guaranty reserve for estimated credit losses for off-balance sheet exposures over the contractual period for which they are exposed to the credit risk, unless that obligation is unconditionally cancellable by the issuer.
Derivatives	We recognize all derivatives as either assets or liabilities in our condensed consolidated balance sheets at their fair value on a trade date basis. Fair value amounts, which are (1) netted to the extent a legal right of offset exists and is enforceable by law at the counterparty level and (2) inclusive of the right or obligation associated with the cash collateral posted or received, are recorded in “Other assets” or “Other liabilities” in our condensed consolidated balance sheets.We present cash flows from derivatives as operating activities in our condensed consolidated statements of cash flows.We record all gains and losses, including accrued interest, on derivatives while they are not in a qualifying designated hedging relationship in “Fair value gains (losses), net” in our condensed consolidated statements of operations and comprehensive income.
Derivatives, Methods of Accounting, Hedging Derivatives	Pursuant to this program, we may designate certain interest-rate swaps as hedging instruments in hedges of the change in fair value attributable to the designated benchmark interest rate for certain closed pools of fixed-rate, single-family mortgage loans or our funding debt. For hedged items in qualifying fair value hedging relationships, changes in fair value attributable to the designated risk are recognized as a basis adjustment to the hedged item. We also report changes in the fair value of the derivative hedging instrument in the same condensed consolidated statements of operations and comprehensive income line item used to recognize the earnings effect of the hedged item’s basis adjustment.
Derivatives, Offsetting	Derivative instruments are recorded at fair value and securities purchased under agreements to resell are recorded at amortized cost in our condensed consolidated balance sheets.
Segment Reporting	We have two reportable business segments, which are based on the type of business activities each perform: Single-Family and Multifamily. Results of our two business segments are intended to reflect each segment as if it were a stand-alone business. The sum of the results for our two business segments equals our condensed consolidated results of operations.
Concentrations of Credit Risk	One of the measures by which we gauge our credit risk is the delinquency status of the mortgage loans in our guaranty book of business. For single-family and multifamily loans, we use this information, in conjunction with housing market and other economic data, to structure our pricing and our eligibility and underwriting criteria to reflect the current risk of loans with higher-risk characteristics, and in some cases we decide to significantly reduce our participation in riskier loan product categories. Management also uses this data together with other credit risk measures to identify key trends that guide the development of our loss mitigation strategies.
Fair Value Measurement	Fair Value Measurement Fair value measurement guidance defines fair value, establishes a framework for measuring fair value, and sets forth disclosures around fair value measurements. This guidance applies whenever other accounting guidance requires or permits assets or liabilities to be measured at fair value. The guidance establishes a three-level fair value hierarchy that prioritizes the inputs into the valuation techniques used to measure fair value. The hierarchy gives the highest priority, Level 1, to measurements based on unadjusted quoted prices in active markets for identical assets or liabilities. The next highest priority, Level 2, is given to measurements of assets and liabilities based on limited observable inputs or observable inputs for similar assets and liabilities. The lowest priority, Level 3, is given to measurements based on unobservable inputs. Fair Value Option We elected the fair value option for loans and debt that contain embedded derivatives that would otherwise require bifurcation. Under the fair value option, we elected to carry these instruments at fair value instead of bifurcating the embedded derivative from such instruments. Interest income for the mortgage loans is recorded in “Interest income: Mortgage loans” and interest expense for the debt instruments is recorded in “Interest expense: Long-term debt” in our condensed consolidated statements of operations and comprehensive income.
Fair Value of Financial Instruments	The fair value of financial instruments we disclose includes commitments to purchase multifamily and single-family mortgage loans that we do not record in our condensed consolidated balance sheets. The fair values of these commitments are included as “Mortgage loans held for investment, net of allowance for loan losses.”
Commitments and Contingencies	On a quarterly basis, we review relevant information about all pending legal actions and proceedings for the purpose of evaluating and revising our contingencies, accruals and disclosures. We establish an accrual only for matters when the likelihood of a loss is probable and we can reasonably estimate the amount of such loss.

Also excludes loans that liquidated either through foreclosure, deed-in-lieu of foreclosure, or a short sale. Loans may move from one category to another, as a result of the restructuring(s) they received during the period. The following tables summarize the financial impacts of loan modifications and payment deferrals made to single-family HFI loans during the three and nine months ended September 30, 2022, presented by class of financing receivable. We discuss the qualitative impacts of forbearance plans, repayment plans, and trial modifications earlier in this footnote. As a result, those loss mitigation options are excluded from the table below.

The following tables display the amortized cost of HFI loans that received a completed modification or payment deferral on or after January 1, 2022, the date we adopted ASU 2022-02, through September 30, 2022 and that defaulted in the period presented. The substantial majority of loans that received a completed modification or a payment deferral during the third quarter of 2022 did not default during the period. For purposes of this disclosure, we define loans that had a payment default as single-family loans with completed modifications that are two or more months delinquent during the period; or multifamily loans with completed modifications that are one or more months delinquent during the period. For loans that receive a forbearance plan, repayment plan or trial modification, these loss mitigation options generally remain in default until the loan is no longer delinquent as a result of the payment of all past-due amounts or as a result of a loan modification or payment deferral. Therefore, forbearance plans, repayment plans and trial modifications are not included in default tables below.

Credit Quality Indicators	The following tables display the total amortized cost of our single-family HFI loans by class of financing receivable, year of origination and credit quality indicator, excluding loans for which we have elected the fair value option. The estimated mark-to-market loan-to-value (“LTV”) ratio is a primary factor we consider when estimating our allowance for loan losses for single-family loans. As LTV ratios increase, the borrower's equity in the home decreases, which may negatively affect the borrower's ability to refinance or to sell the property for an amount at or above the outstanding balance of the loan.

Fair Value of Financial Instruments	The following table displays the carrying value and estimated fair value of our financial instruments. The fair value of financial instruments we disclose includes commitments to purchase multifamily and single-family mortgage loans that we do not record in our condensed consolidated balance sheets. The fair values of these commitments are included as “Mortgage loans held for investment, net of allowance for loan losses.” The disclosure excludes all non-financial instruments; therefore, the fair value of our financial assets and liabilities does not represent the underlying fair value of our total consolidated assets and liabilities.

Broker-Dealer, Net Capital Requirement, SEC Regulation [Abstract]
Regulatory Capital Classification Measures	Capital Metrics under the Enterprise Regulatory Capital Framework as of September 30, 2022 (1) (Dollars in billions) Adjusted total assets $ 4,540 Risk-weighted assets 1,298 Amounts Ratios Available Capital (Deficit) (2) Minimum Capital Requirement Total Capital Requirement (including Buffers) (4) Available Capital (Deficit) Ratio (3) Minimum Capital Ratio Requirement Total Capital Requirement Ratio (including Buffers) Risk-based capital: Total capital (5) $ (53) $ 104 $ 104 (4.1) % 8.0 % 8.0 % Common equity tier 1 capital (94) 58 137 (7.2) 4.5 10.6 Tier 1 capital (75) 78 157 (5.8) 6.0 12.1 Adjusted total capital (75) 104 183 (5.8) 8.0 14.1 Leverage capital: Core capital (6) (62) 113 113 (1.4) 2.5 2.5 Tier 1 capital (75) 113 136 (1.7) 2.5 3.0 (1) Ratios are calculated as a percentage of risk-weighted assets for risk-based capital metrics and as a percentage of adjusted total assets for leverage capital metrics. (2) Available capital (deficit) for all line items excludes the stated value of the senior preferred stock ($120.8 billion). Available capital (deficit) for all line items except total capital and core capital also deducts a portion of deferred tax assets. Deferred tax assets arising from temporary differences between GAAP and tax requirements are deducted from capital to the extent they exceed 10% of common equity. As of September 30, 2022, this resulted in the full deduction of deferred tax assets ($12.7 billion) from our available capital (deficit). Available capital (deficit) for common equity tier 1 capital also excludes the value of the non-cumulative perpetual preferred stock ($19.1 billion). (3) Ratios are negative because we had a deficit in available capital for each tier of capital. (4) The applicable buffer for common equity tier 1 capital, tier 1 capital, and adjusted total capital is the PCCBA, comprised of a stress capital buffer, a stability capital buffer, and a countercyclical capital buffer. The applicable buffer for tier 1 capital (leverage based) is the PLBA. The stress capital buffer and countercyclical capital buffer are each calculated by multiplying prescribed factors by adjusted total assets as of the last day of the previous calendar quarter. The 2022 stability capital buffer is calculated by multiplying a factor determined based on our share of mortgage debt outstanding by adjusted total assets as of December 31, 2020. The prescribed leverage buffer for 2022 is set at 50% of the 2022 stability buffer. Going forward the stability buffer and the prescribed leverage buffer will be updated with an effective date that depends on whether the stability capital buffer increases or decreases relative to the previously calculated value. (5) The sum of (a) core capital (see definition in footnote 6 below); and (b) a general allowance for foreclosure losses, which (i) shall include an allowance for portfolio mortgage losses, an allowance for non-reimbursable foreclosure costs on government claims, and an allowance for liabilities reflected on the balance sheet for estimated foreclosure losses on mortgage-backed securities; and (ii) shall not include any reserves made or held against specific assets; and (c) any other amounts from sources of funds available to absorb losses that the Director of FHFA by regulation determines are appropriate to include in determining total capital. (6) The sum of (a) the stated value of our outstanding common stock (common stock less treasury stock); (b) the stated value of our outstanding non-cumulative perpetual preferred stock; (c) our paid-in capital; and (d) our retained earnings (accumulated deficit). Core capital does not include: (a) accumulated other comprehensive income or (b) senior preferred stock.
